Until now, the bachelor’s program at the Faculty of Electrical Engineering and Information Technology at Chemnitz University of Technology could only be pursued in German, but that is set to change starting in October 2026. That is when the new bachelor’s program in "Digital Engineering" will launch, offering students the opportunity to begin an undergraduate degree in English. In terms of content, the new program is modeled after the established German-language Bachelor’s program in "Electrical Engineering and Information Technology", providing a solid foundation in mathematics, physics, computer science, and electrical engineering and information technology during the first four semesters. Starting in the fifth semester, students then choose one of two specializations "Automation and Control" or "Information and Communication Systems" in which they receive their first in-depth training. Upon successfully completing their studies in one of these promising fields, they will have both the opportunity to enter the job market directly and the qualifications needed to pursue a master’s degree.

What makes this degree program unique is the fact that, in addition to specialized academic training, the teaching and—above all—the practical application of language skills are an integral part of the curriculum. Students who do not already possess the required German language proficiency must reach Level C1 of the Common European Framework of Reference for Languages (CEFR) within the first four semesters. These language skills can then be continuously applied and further developed starting in the fifth semester, as subject-specific courses are taught almost exclusively in German from that point on. An additional benefit of this approach is that it is intended to foster networking with students in German-language degree programs and, above all, to support students' future integration into the German job market.

The admission requirements for the program are a general or subject-specific high school diploma or an equivalent qualification for university admission. In addition, applicants must demonstrate English proficiency at the B2 level of the CEFR and German proficiency at the A1 level of the CEFR.

Enrollment for the winter semester 2026/2027:  International applicants from outside the EU/EEA and Switzerland can still apply for the winter semester 2026/2027 through uni-assist (www.uni-assist.de/en) until 15 July 2026. International applicants from EU/EEA countries and Switzerland may apply until 31 August 2026. German applicants may apply through the Chemnitz University of Technology’s online application portal (https://campus.tu-chemnitz.de) until 18 September 2026.

Who did not make the experience of stress prior to the examinations? In order to assist students of Chemnitz University of Technology to prepare at the best for their examinations, the University Library (UL) offers to them even several opportunities during the central examination period from July 6 to August 15, 2026. During this period, it has not only extended opening hours, from 09:00 am to midnight, but it is additionally open on Sundays during the same time. Furthermore, the UL provides from July 17 on four more teamworks spaces in its „IdeenReich“ in addition to those in the „Common Area“ at the East Wing. However, they have to be booked online before via a reservation system (mytuc.org/hwfc).

Organizational information: Bookings are possible daily for the periods from 9 am to 01 pm, from 01 pm to 5 pm and from 5 pm to 10 pm respectively. For the usage of the additional teamwork spaces at the IdeenReich on Saturdays and Sundays, the booking has to be done the respective Friday before until noon at latest. The working spaces may be used by groups up to 10 persons. However, the registration has to be done by one person serving also as contact person for the UL then.

The information and service desks are not staffed on the seven Sundays within the examination period. This means, that users may work in the UL and also borrow and return media from its collections via the self-checkout and return machines, but may not pay charges or ask for making changes at their user data. This applies also to weekdays from 07 pm to midnight and to Saturdays from noon to midnight. However, in case of inquiries, the guard at the ground floor next to the main entrance may be contacted.

From intelligent industrial robots and autonomous vehicles to automated greenhouses and networked energy systems – automated and controlled systems are increasingly shaping our everyday lives and industrial value creation. As a result, companies in process engineering, mechanical engineering, the automotive industry, electronics, medical technology and many other sectors are seeing a growing demand for engineers with expertise in automation, robotics and control engineering. This is where the new English-language Master’s programme “Automation, Robotics and Control” comes in, which can be studied at Chemnitz University of Technology from the winter semester 2026/27 onwards. Even before the application deadline has passed, there is already strong international interest in the new master's program. 

The programme was designed by the Institute for Automation at the Faculty of Electrical Engineering and Information Technology at Chemnitz University of Technology. “With our new Master’s programme, we are creating an offer that covers the entire chain – from the modelling and control of dynamic systems, through intelligent automation, all the way to implementation on real robots – in an integrated way”, says Dean of Studies Prof. Dr. Stefan Streif. “Here, students do not only learn theory; they also work with modern simulation tools and can directly test what they have learned on experimental setups. This creates a clear practical link from theory to application.”

A central element of the degree programme are the practice-oriented project groups in the second and third semesters. In interdisciplinary teams, students with different academic backgrounds work on complex tasks, for example in the areas of intelligent sensor systems, mobile robotics or automated agriculture. “Our project groups mirror typical working situations in companies”, explains Prof. Dr. Peter Protzel, who co-designed the new programme. “Students learn how to analyse requirements together, design solutions, implement and test them, and present the results convincingly”, Protzel adds.

The admission-free programme is taught entirely in English and is aimed at both international and German-speaking applicants. International students have the opportunity to acquire extensive German language skills as part of the programme. At the same time, German-speaking students deepen their subject-specific English skills. In addition, an accompanying seminar series within the project groups provides space to strengthen soft skills such as academic/scientific work, ethics in technology development and the interaction between humans and technology.

According to the Dean of Studies, graduates of the Master’s programme “Automation, Robotics and Control” are excellently qualified for demanding positions in research and development, project management or system integration – both in Germany and internationally. “Through the close linkage of theoretical foundations, practical lab work and interdisciplinary projects, the programme opens up excellent career prospects in industrial companies, research institutes and for a subsequent doctorate”, says Streif.

Enrollment for the winter semester 2026/2027:  International applicants from outside the EU/EEA and Switzerland can still apply for the winter semester 2026/2027 through uni-assist (www.uni-assist.de/en) until 15 July 2026. International applicants from EU/EEA countries and Switzerland may apply until 31 August 2026. German applicants may apply through the Chemnitz University of Technology’s online application portal (https://campus.tu-chemnitz.de) until 18 September 2026.

The International Conference on Machine Learning (ICML) is considered one of the most important international conferences in machine learning, a subfield of artificial intelligence. The conference is highly competitive: this year, only 6,352 out of 23,918 submitted papers were accepted. Among the accepted contributions is a paper from the ESF PLUS junior research group “Human-Understandable, Optimal Resource and Energy Management for Complex, Network-Integrated, Biogenic Production Systems” (MORE-KIBA) at Chemnitz University of Technology, led by Prof. Dr. Stefan Streif, Professorship of Automatic Control and System Dynamics.

Causally grounded and human-understandable explanations for optimal predictive control

The accepted paper, titled “Hierarchical Causal Abduction: A Foundation Framework for Explainable Model Predictive Control”, addresses a central question of MORE-KIBA. Model Predictive Control (MPC), widely used in control engineering, is applied in many domains where resource consumption must be optimized, such as energy systems, building climate control, and process or biotechnological systems.

“Due to nonlinear process dynamics, strict safety constraints, and the complexity of numerical optimization procedures, time-dependent control decisions are often very difficult for operators to understand,” says Streif. “This significantly reduces trust in the control system and often leads to it being switched off and replaced by manual operation. This, in turn, results in efficiency losses and unnecessary resource consumption.”

He continues: “With Hierarchical Causal Abduction, we present a framework that combines three complementary sources of evidence: physics-based knowledge from knowledge graphs of the underlying process model, auxiliary variables from the optimizer, and temporal causal dependencies. By integrating these sources, reliable and human-interpretable explanations for the decisions of nonlinear MPC can be derived.”

The approach was evaluated in three applications: greenhouse climate control, a heating and ventilation system for a residential building, and a process engineering system. Validated by domain experts, the method improves explanation quality by 53 percent compared to other AI-based explanation approaches. The quality of explanations can be further significantly improved with additional data and training. Moreover, the approach is easily transferable to other processes and applications controlled by predictive control methods.

“The acceptance of this Chemnitz contribution at ICML 2026 highlights the international visibility of the group’s research on trustworthy and explainable AI for engineering applications,” Streif concludes.

Background: Junior Research Group MORE-KIBA

The junior research group “Human-Understandable, Optimal Resource and Energy Management for Complex, Network-Integrated, Biogenic Production Systems” (MORE-KIBA) addresses a pressing challenge in sustainable industrial production. In times of limited resources, complex systems must be operated optimally, yet the underlying mathematical algorithms are often difficult for operators to understand. As a result, potential for sustainable operation is lost or promising technologies are not adopted.

The goal of MORE-KIBA is to make algorithmic decisions transparent and understandable using AI. The approach is demonstrated using a biorefinery coupled with an energy network simulator. Applicability is ensured through collaboration with various stakeholders from industry in Saxony.

The project is funded with more than € 2.13 million through the European Social Fund Plus program. Seven early-career researchers from four faculties at TU Chemnitz are involved.

Only 20 projects nationwide were selected by the German Academic Exchange Service (DAAD) in the competitive "Academic Horizons" programme and Chemnitz University of Technology is among the winners, as the only higher education institution in Saxony to secure funding in this call. With a budget of 750,000 euros over 3.5 years, the project "AI GlobalMinds – Global Minds Advancing Next-Generation Sustainable AI for Innovation Leadership" stood out through its comprehensive integration concept, holistic AI education approach across the complete value chain, effective mobilization of existing DAAD partnerships and international networks, and strategic diversification of recruitment channels for Master's students and PhD candidates.

Running from May 2026 to December 2029, AI GlobalMinds addresses a critical challenge: Germany's growing shortage of qualified specialists in artificial intelligence. The project aims to diversify the recruiting channels for students and PhD candidates by creating structured international talent pathways, combining targeted recruitment from Chile, Tunisia and Serbia, and with academic qualification and practical integration into the German innovation ecosystem. TU Chemnitz will build new recruiting channels and advertising strategies to showcase its excellent education programs around AI from data acquisition and sensor technology, through AI methods and neuromorphic computing, to sustainable and Green AI applications in science and different economic sectors.

"AI GlobalMinds addresses a key challenge for Germany's innovation system," explains Prof. Dr. Olfa Kanoun, project coordinator at the Chair of Measurement and Sensor Technology. "The demand for AI expertise is growing rapidly, while qualified professionals remain scarce. By connecting international recruitment with structured qualification and integration, we create opportunities for both AI talents and Germany's innovation landscape."

From Sensors to Intelligent Systems: Comprehensive AI Education

What distinguishes AI GlobalMinds is its holistic approach to AI education. Rather than focusing on isolated algorithms, participants gain system-level understanding across the full AI value chain from sensor-based data acquisition to intelligent processing and real-world implementation in neuromorphic systems and robotics, with particular emphasis on sustainable and Green AI approaches.

“Neurorobotics represents the convergence of brain-inspired computing, embodied AI, and intelligent sensor systems,” explains Florian Röhrbein. “By bringing together international talent with diverse backgrounds in these complementary fields, we are building the interdisciplinary teams needed to advance intelligent systems that can truly interact with and learn from their environment — while also addressing energy efficiency and sustainability aspects that are crucial for the future of AI.”

The project brings together multiple faculties at TU Chemnitz: Electrical Engineering and Information Technology, Computer Science, and Mathematics alongside central institutions including the International University Center and Career Service.

Comprehensive Support: From Arrival to Career

"Successful international recruitment requires more than academic excellence it demands comprehensive support throughout the entire journey," emphasizes Katharina Wohlgemuth from the International University Center. "AI GlobalMinds provides exactly this: structured pre-arrival preparation, coordinated onboarding, buddy program, accelerated German language training, and continuous mentoring to ensure participants thrive both academically and socially in Chemnitz."

The project explicitly prepares participants for both academic and industry careers in Germany. "Germany's AI ecosystem needs qualified professionals across all sectorsfrom university research groups to innovative companies and applied research institutions," adds André Zwingenberger Claren from the Career Service. "Through targeted skills workshops, networking events with AI experts and industry representatives, and intercultural workplace training, we prepare AI GlobalMinds participants not just technically, but also for the realities and expectations of the German professional environment."

Building on established partnerships with universities in Tunisia, Serbia, and Chile, the project creates sustainable recruitment structures while strengthening international cooperation and diversifying TU Chemnitz's talent pipelines.

Background: Project "AI GlobalMinds"

AI development demands more than algorithms, it requires integrating data acquisition, hardware, and realworld implementation. AI GlobalMinds spans this full spectrum: from sensor technology through machine learning to sustainable Green AI applications. The project combines short-term orientation formats with longer study and research stays, allowing early identification of talent and gradual integration into academic and professional pathways in Germany. Students are introduced to research environments, work on practical topics, and gain experience in applying AI methods in realistic scenarios—from intelligent sensor systems to neuromorphic computing and autonomous robotics, with emphasis on energy-efficient and sustainable implementations.

At the same time, AI GlobalMinds strengthens existing international partnerships and contributes to the development of sustainable structures for recruiting and qualifying talent. By diversifying recruitment channels and building new pathways for international students and PhD candidates, the project supports Germany's long-term goals in innovation and artificial intelligence development.

A Franco-German research team of members of the FEMTO-ST Institute at the Université Marie et Louis Pasteur, Besançon, as well as the Faculties of Electrical Engineering and Information Technology and Natural Sciences, and the Research Center for Materials, Architectures and Integration of Nanomembranes (MAIN) at Chemnitz University of Technology, have uncovered new insights into the formation of forbidden frequency bands in periodic solid-state structures. The study, titled “Contact points open wide band gaps in all two-dimensional Bravais lattices,” was published in late April in the physics journal Physical Review B and makes fundamental contributions to the understanding of the electromagnetic wave transport properties through regularly arranged materials.

This study examines the influence of contact points between copper tubes as individual scatterers arranged regularly in space on the propagation of radio waves and, consequently, on the formation of forbidden frequency regions for these waves—so-called band gaps. Using theoretical considerations, numerical simulations, and experimental measurements of scattering across all possible two-dimensional arrangements—known as Bravais lattices—of the tubes, the researchers demonstrate that contact points systematically generate wider band gaps, thereby enabling broadband filters for radio-frequency waves.

The results underscore that a precise understanding of the geometric structure of the scatterers and their exact positioning relative to one another, especially in the case of touch, can systematically influence and control the band structures, thereby helping to control and tailor the propagation of waves. Large, adjustable band gaps are of crucial importance, particularly for applications in electronics and photonics, as they determine the electrical and optical behavior of the components.

This study is part of the current research on the development of geometric effects in functional, two-dimensional membrane materials and is consistent with findings from previous research in which the authors demonstrated a similar effect for sound. It is inspired by work conducted as part of the TUCculture initiative on the stele artwork “Model of Thought and Perception for the Phenomenon of Color” by Dresden-based artist Stefan Nestler (1998), located in front of the Central Lecture Hall and Seminar Building at Chemnitz University of Technology. This artwork has been discovered as the world’s largest realization of a photonic crystal. By further developing this field, the authors are now making a positive contribution to basic research in the field of wave physics and providing a new impetus for materials research.

At the 23rd International Multi-Conference on Systems, Signals and Devices (SSD’26), held March 30 to April 2, 2026, in Catania, Italy, Dr. Ahmed Yahia Kallel, research associate and group leader for Impedance Spectroscopy and Measurement Systems at the Chair of Measurement and Sensor Technology (headed by Prof. Dr. Olfa Kanoun) at Chemnitz University of Technology, received the Best Paper Award.

Lithium-ion batteries are the backbone of electric mobility and stationary energy storage. To reliably determine their state of charge, researchers use Electrochemical Impedance Spectroscopy (EIS), a method that measures a battery’s electrical behavior across different frequencies and generates up to 480 data points per measurement – far too many for the small microcontrollers in battery management systems to process in real time. The award-winning paper “Fast A*-mRMR for Model-Aware Feature Selection in EIS-Based Battery State of Charge Estimation” addresses this challenge through intelligent pre-selection of the most informative data points. The method transfers the A* algorithm – a proven tool in robotics and game development for efficiently finding optimal paths through complex environments – to the domain of feature selection. Rather than exhaustively testing every possible feature combination, the algorithm identifies the best selection directly and efficiently, much like a navigation system finds the shortest route without driving down every road. Two criteria are considered simultaneously: how informative a data point is for predicting the state of charge, and how much it overlaps with already-selected points (Minimum Redundancy Maximum Relevance, mRMR).

Tested on physics-based digital twin data from four battery cells across 17 state-of-charge levels and three temperatures (756 measurement points in total), Fast A*-mRMR achieves a prediction accuracy of 3.62 to 3.93 % error with a computation time of just 1.27 seconds – more than 500 times faster than comparable methods while matching or exceeding their accuracy. The work also yields a counterintuitive insight: allowing a controlled degree of similarity between selected data points can actually improve predictions, contrary to the prevailing assumption that redundancy should always be minimized. “Our method enables the practical use of high-dimensional impedance data in resource-constrained embedded systems, laying an important foundation for more efficient and reliable battery management systems,” explains Dr. Ahmed Yahia Kallel. “The Best Paper Award is a gratifying recognition that our work in intelligent sensor systems and sustainable energy technologies is resonating with the international research community,” adds Prof. Dr. Olfa Kanoun.

The SSD is an established IEEE international multi-conference founded in 2001, bringing together research in the fields of systems, signal processing, and devices, with an H-index of 35. The award was presented at the sub-conference Power Systems & Smart Energies (PSE). The proceedings are published in IEEEXplore and indexed in Scopus and Web of Science.

The question of "What binds the world in its innermost core?" was on Johann Wolfgang von Goethe's mind in "Faust." Many researchers at Chemnitz University of Technology also search for answers to this question. At the new Transmission Electron Microscopy Center (TEM-Center), officially opened on April 14^th, 2026, at Erfenschlager Straße 73 in Chemnitz, researchers aim to visualize structures smaller than the wavelength of visible light. This will enable them to identify atoms, molecules, and the bonds of matter. To achieve this, they will utilize the top-tier research infrastructure.

High-resolution microscopes enable precise material analysis

"The core of the new, single-story building are two highly sensitive transmission electron microscopes that allow us to examine the structure and properties of materials at the molecular and atomic levels, and then translate these findings to new applications," says Prof. Dr. Andreas Undisz, the Chair of Electron Microscopy and Microstructural Analysis at Chemnitz University of Technology and head of the new center. For example, processes that lead to material damage can be examined in very detail, enabling more accurate conclusions to be made about the durability and performance of components.

A worthwhile investment at Chemnitz University of Technology

"With this new building and the two electron microscopes, Chemnitz University of Technology is once again at the forefront of global materials research. The complex technical features offered by this facility as a whole can be found at only a few other locations worldwide. In addition to the three faculties, partner institutions will also benefit. This makes Chemnitz University of Technology even more attractive to top researchers from around the world. Thus, we strengthen the entire scientific region of Southwest Saxony,” said Saxony’s Minister of Science, Sebastian Gemkow, in a statement from the State Ministry of Finance.

"We at Chemnitz University of Technology are delighted to celebrate the opening of the Transmission Electron Microscopy Center. This is an important investment in Chemnitz University of Technology and, by extension, in Chemnitz as a research hub, in our core competencies in materials science and intelligent systems, and in our university’s national and international reputation. We are very grateful to the Free State of Saxony and to everyone involved who actively supported the establishment of the center," says Prof. Dr. Gerd Strohmeier, President at Chemnitz University of Technology. Prof. Dr. Anja Strobel, Deputy President and Vice President for Research and University Development at Chemnitz University of Technology, who represented the Rector in receiving the key, added: "The new Transmission Electron Microscopy Center, which brings together expertise from various research areas at Chemnitz University of Technology, significantly strengthens our university’s STEM field in research and teaching and creates highly attractive conditions for new interdisciplinary research projects as well as for recruiting and training our next generation of academics by providing researchers and students with access to the latest technologies and methods in materials science."

Technological marvels explore the nano cosmos

The electron microscopes, which tower over four meters, capture images of the tiniest structures at the nanometer level. "To ensure these sensitive marvels of technology can operate optimally, they are housed in specially shielded, climate-controlled rooms and rest on a 1.4-meter-thick vibration-damping concrete slab," explains Undisz. This keeps mechanical, acoustic, electromagnetic, and thermal sources of interference at a distance. Experiments using the large-scale research equipment in the protected inner core of the building are conducted remotely from operating rooms. In-depth material analysis using the two transmission electron microscopes requires preparing material samples just a few nanometers thin. This process is semi-automated in an adjacent room using a focused ion beam system.

Researchers from over 20 professorships will work with the equipment in the future

The new center has the advantage of merging all of Chemnitz University of Technology’s high-resolution transmission electron microscopy equipment in one location. More than 20 professorships of the faculties of mechanical engineering, natural sciences, and electrical engineering and information technology will use the equipment for their transdisciplinary and interdisciplinary basic and applied research. They will also collaborate with non-university research institutions, such as Fraunhofer Society institutes, as well as companies.

Background: Transmission Electron Microscopy Center at Chemnitz University of Technology

Construction of the new research building began in September 2023 under the direction of the State Office for Saxon Real Estate and Construction Management. The building was designed by Heinle Wischer Partnership of Independent Architects mbB in Dresden. The sculpture "Impact", created by Stefanie Welk from Walldorf near Heidelberg as part of the "Art in Architecture" competition, frames the building’s entrance.

Approximately 13.1 million euros were invested in the construction of the building. Of this amount, approximately 7.4 million euros were provided by the European Regional Development Fund and around 5.7 million euros by the Free State of Saxony. The project was co-financed with tax revenues based on the budget approved by the Saxon State Parliament. The German Research Foundation (DFG) and the Free State of Saxony each provided 3.5 million euros for the large-scale equipment. Professors Christoph Tegenkamp, Martin Wagner, and Bernhard Wunderle successfully acquired the funding on behalf of the three participating faculties at Chemnitz University of Technology.

Since the launch of the European University Alliance „Across – European University for Cross-Border Knowledge Sharing“ in March 2025, Chemnitz University of Technology has been working with nine partner universities across Europe. More than 30 students and staff from TU Chemnitz are involved in 16 international task forces. These teams develop joint strategies in the areas of education, research, innovation, governance, and societal engagement—creating direct added value for the university. Students and staff at TU Chemnitz are now invited to contribute their experiences on 18 and 20 March 2026 and support one of the task teams with their knowledge.

Supporting the task team by collecting valuable user experiences

Task Team 2.1 – „Across Border Campus System“ is responsible for ensuring the interoperability of digital services across all Across universities. At the core of this work is the “Across eCampus”, a digital hub for management, teaching, learning, and networking. In two moderated focus groups, the task team will collect experiences from everyday study and work routines with the university’s digital systems on 18 and 20 March. These insights will feed into the further development of a digital infrastructure designed to facilitate international collaboration and open up new opportunities for education and exchange. Key questions include: Where does access to information and services already work well? Where do barriers arise (e.g., due to scattered information, unclear processes/responsibilities, or parallel tools)? And which improvements would be most important from a user perspective?

Students and staff at TU Chemnitz who would like to contribute to shaping a future-oriented campus system are warmly invited to take part in the focus groups:

• Student focus group: 18 March, 13:00 (duration: 60–90 minutes; venue: Welcome Center, International University Centre (IUZ), Bahnhofstraße 8)
• Staff focus group: 20 March, 10:00 (duration: 60–90 minutes; venue: Welcome Center, International University Centre (IUZ), Bahnhofstraße 8)

Participation requirements and compensation

Students and staff of Chemnitz University of Technology can participate if they are willing to share experiences in a moderated group discussion and provide feedback on the beta version and concept ideas. No technical background is required. Focus group participants will receive 15 EUR compensation, an official certificate of attendance from the Across alliance, and—optionally—the opportunity to be involved in the future as a „premium beta user“ (early access and further feedback opportunities).

To register interest, students and staff are asked to complete a short pre-survey in advance. Based on the responses, eight to ten participants per focus group will be selected to ensure a broad range of perspectives. For students, selection aims to cover different faculties, study programms, and stages of study. For staff, selection will consider different roles as well as experience with various internal digital systems. Anyone who is interested but cannot attend on the scheduled dates can, upon request, be contacted again for the next development phases of the „Across eCampus“.

Keyword: Across eCampus

The „Across eCampus” is intended as a central digital access point of the Across university alliance to make study- and work-related services easier to use across institutions. This applies in particular to access to course content and learning offers from partner universities, as well as information and services that facilitate international exchange and mobility. In the long term, a dashboard will serve as the central entry point, bundling user-related information and simplifying access to core services. These include, for example, a digital course catalogue and a learning environment for cross-institutional digital and blended-learning formats, as well as collaboration and communication tools. Within the Across alliance’s „eCampus” sub-project, a digital infrastructure is being developed to centrally bundle and integrate existing services rather than replace them.

Dr. Chundong Wang, Professor at Huazhong University of Science and Technology in Wuhan (China), has been awarded a research fellowship for experienced scientists by the Alexander von Humboldt Foundation. The prestigious fellowship will enable him to conduct a one-year research stay at the Chemnitz University of Technology, starting in March 2026. At the Research Centre for Materials, Architectures and Integration of Nanomembranes (MAIN), he will work in the group of Dr Minshen Zhu at the Professorship of Material Systems for Nanoelectronics (Chair: Prof. Oliver G. Schmidt) in the Faculty of Electrical Engineering and Information Technology. 

Wang's research focuses on electrocatalysis and nanostructured functional materials, particularly for sustainable energy technologies such as hydrogen production and fuel cell technology. The aim of his work is to understand catalytic reactions at the atomic level and to develop advanced catalysts with precisely controlled electronic structures. In particular, he investigates single-atom catalysts and the role of electronic spin states in governing catalytic performance.

During his research stay in Chemnitz, Wang will collaborate with the groups of Dr Zhu and Prof Schmidt to develop microfluidic strategies for the controlled synthesis of single-atom catalysts at the MAIN Research Centre. The project aims to understand the influence of the electronic spin configuration of transition metal centres on catalytic reaction pathways and kinetics. By combining concepts from electrochemistry, nanotechnology and microfluidic technology, the aim is to enable more efficient and cost-effective production of catalysts. The expected results could contribute to the development of high-performance hydrogen fuel cell technologies, which are considered a key factor for sustainable energy systems.

On February 5, 2026 from 04:00 pm on, it happens again: The University Library jointly with the University Computer Center, the Foreign Language Center, the Methodological Competence Center of the Faculty of Behavioral and Social Sciences, the Central Course Guidance Service as well as the Student Council, the faculty student bodies and the Student Union Chemnitz-Zwickau invites again for the “Long Night of Postponed Course Papers”. The concept was adapted to the demands of the students. Thus, this year is provided the opportunity to book in advance individual time slots of 20 minutes for consultation with the respective consultant at the information booths according to the own time planning and orienting at the personal inquiries and needs via OPAL (mytuc.org/gsxv). The information booths provide their offers at the west wing at the ground floor of the Library Building until 10:00 pm.

In order to create the best conditions for finally complete the course paper, also sufficient opportunities for relaxing are provided: Thus, at 05:45 pm and at 08:00 pm a “break for moving” of respectively 15 minutes is offered at the east wing at the ground floor and within the period from 06:00-08:00 pm four times yoga and relaxing exercises of respectively 20 minutes (in the IdeenReich). From 07:00-09:00 pm, twelve time slots for “speed massages” of respectively ten minutes are provided. Those are allocated from 05:00 pm on at the information booth of the Student Union – first come, first serve! For the “breaks for moving” as well as for the yoga and relaxing exercises on the contrary, no prior registration is required. Thanks to the Student Union, also food and beverages are provided.

The event is rounded off by a keynote speech of Sofie Marie Götz of the Junior Professorship Sociology with Specialization in Technology dealing with the topic “Apply Generative AI (right) within studies” in the IdeenReich.

Subsequently, from 10:00 pm on, the course paper may be elaborated – this time, however, not only until midnight but all around the clock as until February 14, 2026 midnight, the University Library stays open 24/7 for the first time and thus fulfills a wish frequently expressed by its users. Consequently, not only the “course paper authors” but all students are cordially invited to extensively make use of this offer and crowd the University Library also during the night within the period mentioned. Please observe to bring with you your TUCcard as you will need it for getting in the Library Building within the time from midnight to 09:00 am by presenting it to a scanning device next to the main entrance.

From December 1 to 4, 2025, the final week of the three-year collaborative project „WeSPICE" took place at the Tunisian university École Nationale d'Electronique et de Télécommunications de Sfax (ENET'COM). The project was funded by the German Academic Exchange Service (DAAD) as part of the Ta'ziz Partnership Program. The following staff members from the Chair of Measurement and Sensor Technology at Chemnitz University of Technology were involved in the project: Prof. Dr. Olfa Kanoun (Chair holder), Dr. Thomas Keutel (Project Manager Impedance Spectroscopy), Dr. Christian Viehweger (Working Group Leader and Project Manager Energy-Autonomous Sensor Systems), Dr. Rim Barioul (Working Group Leader Smart Wearables), Dr. Hiba Hellara (Project Manager Smart Wearables), and Mohamed Dhia Ayadi (Project Leader Micro- and Nanosensors (Nanogenerators)). The project was officially concluded with all participating organizations on December 4, 2025, in a ceremonial closing event attended by representatives from TU Chemnitz and the German Embassy in Tunis, as well as the Director of the DAAD Country Office.

Cross-Border Professional Development and Student Orientation

TU Chemnitz and ENET'COM in Sfax have worked closely in recent years with the Dräxlmaier Group, headquartered in Vilsbiburg, Lower Bavaria. The globally renowned premium vehicle manufacturer develops and produces wiring systems, electrical and electronic components, battery systems, and high-quality interiors for premium automotive manufacturers such as BMW and Porsche.

The project pursued three central thematic priorities with a special focus on knowledge transfer, participatory network building, and sustainable dialogue between academia, industry, and society:

• Professional development in ASPICE (Automotive SPICE): A total of 17 professionals were qualified, including seven instructors who will directly incorporate their knowledge into university teaching in the future, thereby ensuring sustainable knowledge transfer from industry to academia.
• Building an interdisciplinary network: A network of 25 partners from industry and society was established. Together with these non-university actors, „Improvements of Engineering Education Addressing Industry and Research Needs" were discussed from the perspectives of instructors and students. These participatory dialogue spaces enabled knowledge exchange between academia and practice and contributed to the needs-oriented development of engineering education.
• Student-oriented events: Over 360 students participated in a total of 32 participatory events including hackathons, soft skills seminars, women's empowerment workshops, job fairs, and green economy workshops. These formats strengthened the dialogue between universities, industry, and civil society and created sustainable bridges between academic education and professional practice.

ASPICE is an internationally recognized process model for evaluating and improving development processes in the automotive industry. Manufacturers and suppliers worldwide use it to ensure the quality, safety, and efficiency of software and system development. The project's final week was framed by a job fair and a workshop on integrating ASPICE into academic teaching. This made the international collaboration between research, industry, and education clearly visible and strengthened once again. „The parallel qualification of instructors and the practice-oriented offerings for students represent a sustainable contribution to strengthening international cooperation and training future professionals," emphasizes Prof. Dr. Olfa Kanoun, project leader on the German side.

Background: The WeSPICE Project

The collaborative project „We Establish Sustainable Program to Improve Commitment to Employability" (WE-SPICE)" was funded from 2023 to 2025 by the German Academic Exchange Service (DAAD) as part of the Ta'ziz Partnership Program with approximately 300,000 euros from the German Federal Foreign Office.

Background: Ta'ziz Partnership Program

The Ta'ziz Partnership Program, funded by the German Academic Exchange Service (DAAD) with resources from the Federal Foreign Office, promotes cooperation between German universities and partner institutions in the MENA region (Middle East and North Africa). The Arabic term  „Ta'ziz" means „strengthening" or  „consolidation" and clarifies the program's objective. In times of social and political change, universities and non-university actors are to be supported in order to promote reforms, scientific cooperation, and civil society participation.

The Physik Journal, the member magazine of the German Physical Society (DPG, Deutsche Physikalische Gesellschaft e. V.), the most important specialist medium and central information forum for over 50,000 physicists of all disciplines in German-speaking countries, features an overview article in its January 2026 issue on two projects from the TUCculture2025 initiative of Chemnitz University of Technology in recent years that have combined art and physics in a special way. For example, the stele artwork “Thinking and Perception Model for the Phenomenon of Color” by Dresden artist Stefan Nestler, erected in 1998 as part of the construction of the Central Lecture Hall and Seminar Building at Chemnitz University of Technology, demonstrated how abstract concepts of modern physics can be explored through aesthetic experience. From the viewpoint of the end of 2025, the article puts the European Capital of Culture Chemnitz again into a retrospective focus.

Behind a largely regular arrangement of 187 metal steles, which have adorned the forecourt of the Central Lecture Hall and Seminar Building as a work of art since 1998, lies more than just an aesthetic object: it represents a kind of color in itself, a variation on what it conveys as its main message. What sounds like a somewhat convoluted but trivial statement is the result of more than three years of intensive and interdisciplinary scientific observation, funded in part by the projects “Chemnitz: Wood, Light, Sound” and “Wave Plays” as parts of the TUCculture2025 initiative. The work revealed that the artwork “Thinking and Perception Model for the Phenomenon of Color” is the world's largest scientifically described realization of a photonic crystal for electromagnetic waves and, at the same time, represents a phononic crystal that can be used fort he manipulation of sound waves. It thus represents forbidden regions, i.e., barriers for waves in several spectral ranges: the band gaps occur for both sound and radio waves, so that the artwork has its own “color” in each of these two domains.

This special connection between physics, art, and the worlds of human perception and metrological measurement is the focus of the overview article titled “Phoxonic Art” Herein, Prof. Dr. Angela Thränhardt, Professor of Theoretical Physics at Chemnitz University of Technology and Dean of the Faculty of Natural Sciences, and Dr. Thomas Blaudeck, Managing Director of the Research Center for Materials, Architectures, and Integration of Nanomembranes (MAIN) at Chemnitz University of Technology, explain how Stefan Nestler's stele arrangement allowed fundamental wave equations to be examined clearly and how numerical simulations, theoretical models, and metrological experiments were interlinked with the expertise of the faculties of Natural Sciences and Electrical Engineering and Information Technology. The adjective “phoxonic” in the deliberately pejorative title “Phoxonische Kunst” (Phoxonic Art) refers to the fact that several “forbidden regions” for the propagation of waves, i.e., band gaps, occur in one and the same object. This applies both to the photonic case, i.e., that related to light and electromagnetic waves in the field of established communication technologies, and to the phononic case, i.e., that are related to acoustics and hence sound. An interaction between these domains is also conceivable, at least in principle. This demonstrates the remarkable visionary nature of artist Stefan Nestler, who has imbued his artwork with a unique, phoxonian model of perception that is measurable and therefore verifiable.

The overview article also highlights that physical research not only unlocks new insights into abstract or complex phenomena in nature, but also opens up innovative avenues for science communication through its connection with art: as part of the TUCculture2025 projects, the artwork and its surroundings were transferred to a laboratory environment where the complex wave phenomena of photonics and phononics, such as scattering, interference, and diffraction, became audible and tangible in surprising ways. The artwork thus became the starting point for dialogue between scientists, friends of art, and the general public, for example at the Open House Days (TUCtage) since 2022 or the Christmas market at Chemnitz University of Technology. This is an example of bringing physics out of the “ivory tower” and into the urban and cultural space.

Beyond the specific topic, the overview article provides an outline of other projects with a “physical flavor” from the TUCculture2025 initiative of Chemnitz University of Technology, which since 2022 has bundled many of the university's activities at the interface of science, art, and society since 2022 and was geared toward 2025, when Chemnitz held the title of “European Capital of Culture.” The article also looks back on cultural projects and events in Chemnitz during the European Capital of Culture year that had a special connection to physics and thus became part of the broad cultural program in Chemnitz as scientific sprinklings.

The article has been available as a summary on the Physik Journal website (issue 01/2026) since January 5, 2026 (login required to access the PDF).

Can you tell us a little bit about yourself?

I came from Mongolia. I graduated from the Mongolian University of Science and Technology (MUST) in 2014 with a bachelor’s degree in Computer Hardware Engineering. Since 2023, I have begun my master’s research in the rapidly advancing field of Artificial Intelligence, one of the most dynamic areas in today’s technological world. I am very pleased to have been selected for the “Saxon Student Mobility Program” and to have joined Chemnitz University of Technology in May 2025 as a visiting research master's student.

What brought you to Chemnitz and what are you currently doing at Chemnitz University of Technology? 

I learned about the "Saxon Student Mobility Program” through an announcement posted on the official website of MUST. After successfully passing the selection, I came to Chemnitz University of Technology as a research master’s student to produce an internationally recognized research paper in my chosen field of study. My research work involves studying a wide range of methods in AI and machine learning, as well as image processing, and exploring how these can be applied to solving real-world problems. For instance, I am working on the development of a mobile application capable of detecting various types of skin cancers and lung cancers.

What is your impression of the city and its university?

Chemnitz is a city with a rich history and remarkable beauty. Upon my arrival, I found it to be safe for foreigners, characterized by abundant green spaces, a tranquil atmosphere, friendly residents, and a highly developed public transportation system. I have been thoroughly impressed by the university’s campus, research laboratories, library, and surrounding environment. The abundance of research laboratories and the extensive collection of resources in the library provide significant advantages for student learning.

What has been your highlight so far?

I was pleasantly surprised to learn that many students at the university were already familiar with Mongolia. For instance, they spoke about Chinggis Khaan, Ulaanbaatar city, and the Mongolian countryside. I have had the opportunity to gain knowledge from excellent professors, connect with international students, build meaningful friendships, and explore various aspects of myself. These experiences have made my time here both enriching and memorable.

What will you do after your stay at Chemnitz University of Technology? What are your plans?

During my time at Chemnitz University of Technology, I am working on completing my master's thesis. Upon returning to Mongolia, I plan to finalize and defend my master's degree as soon as possible. My future goal is to return to Chemnitz University of Technology to pursue doctoral studies. I also intend to share the knowledge and experience I have gained with students in Mongolia.

In a major step toward intelligent and collaborative microrobotic systems, researchers at the Research Center for Materials, Architectures and Integration of Nanomembranes (MAIN) at Chemnitz University of Technology have developed a new generation of autonomous microrobots—termed smartlets—that can communicate, respond, and work together in aqueous environments.

These tiny devices, each just a millimeter in size, are fully integrated with onboard electronics, sensors, actuators, and energy systems. They are able to receive and transmit optical signals, respond to stimuli with motion, and exchange information with other microrobots in their vicinity. The findings are published in the prestigious journal Science Robotics under the title “Si chiplet–controlled 3D modular microrobots with smart communication in natural aqueous environments”. Unlike previous generations of microrobots that relied on much larger wireless control setups to mitigate limited onboard functionality, smartlet microrobots are powered by integrated photovoltaic cells, controlled by tiny microchips, and capable of optical communication through embedded micro-LEDs and photodiodes. "For the first time, we demonstrate a self-contained microrobotic platform that not only senses and moves in water but also interacts with other microrobots in a fully programmable and autonomous manner," explains Prof. Oliver G. Schmidt, one of the corresponding authors of the study and Scientific Director of MAIN.

The microrobots are built using a flexible origami-inspired approach, based on smart multilayer patterned materials, allowing the flat electronic system to roll and fold up autonomously into a tiny scroll-adorned hollow 3D cube, with interior as well as exterior functionality. This opens up the extra surface space needed for each cube to carry its own solar energy harvester, computational logic, and an optical signaling system, in addition to interacting external faces and inboard locomotion. When immersed in water, these smartlets can move up and down by buoyancy forces created by bubble generating engines that fill the hollow interior of the smartlet with gas. They can also emit pulses of optical signals to broadcast instructions to other smartlets nearby. This setup enables multi-robotic interactions in water, including stimulus-driven movement, synchronization, and coordination among multiple smartlets. For example, when one unit receives a light signal, it can decode the information using its onboard processor, triggering a coordinated motion or behavior in others. “The idea of using light as both energy and information opens up a compact and scalable way to create distributed robotic systems,” adds Dr. Vineeth Bandari, co-corresponding author and research group leader at MAIN.

One of the key innovations lies in the smartlets’ use of a “wireless communication loop” that does not require any external cameras, magnets, or antennas. Optical messages are interpreted locally on each robot using custom-coded logic stored on their microchips. The smartlets make use of innovative soft-bonding to origami-films to attach custom microscopic silicon chiplets, called lablets, which were developed in an earlier European Union funded project led by Prof. Dr. John McCaskill, a co-corresponding author and member of MAIN. This permits decentralized control and collaboration—an essential foundation for creating robotic collectives that behave in a coordinated yet flexible way.

Beyond the laboratory, the potential applications of such microrobots are wide-ranging. Because they are untethered, biocompatible, and able to respond to environmental cues, these devices could one day assist in tasks such as monitoring water quality, performing minimally invasive medical diagnostics, or probing confined biological environments. Their ability to form interactive, stimulus-responsive colonies could also be used in soft robotics, autonomous inspection systems, or distributed sensing networks. Dr. Yeji Lee, co-author and specialist in active multi-layer microfabrication, whose recently completed PhD research provided vital contributions, emphasizes that this work is just the beginning. “We’re exploring ways to further increase autonomy by adding chemical and acoustic sensing modules. These smartlets could evolve into multifunctional platforms that sense, act, and adapt in complex fluidic environments.”

Looking forward, the team envisions the progressive evolution of these microrobots into dynamic systems that resemble colonies of digital organisms. Much like zooids in colonial animals such as siphonophores, each smartlet can serve a specialized function—sensing, communicating, moving—and together form an emergent robotic organism. “We’re still far from creating artificial life,” cautions Prof. John McCaskill, who was a founding Director of the European Center for Living Technology in Venice, “but we are starting to see how distributed intelligence and modular hardware can build systems that begin to mirror the adaptive, communicative behaviors of living collectives.” By building such self-contained, communicative microrobots, the Chemnitz team is not only addressing fundamental challenges in microrobotics but also laying the groundwork for future systems that operate, evolve, and perhaps even self-organize—inside water droplets, tissue scaffolds, or miniature ecosystems.
