A research team at Chemnitz University of Technology has developed a flexible nanocomposite film that uses two physical effects in one material. Under mechanical load it generates electrical charge through the piezoelectric effect. At the same time, it changes its electrical resistance through the piezoresistive effect. The material combines the polymer polyvinylidene fluoride (PVDF) with ceramic barium titanate (BaTiO₃) particles and multi-walled carbon nanotubes (MWCNTs). The results have been published in Nano Energy, one of the leading international journals in the field of energy materials and nanotechnology.

Two sensing principles in a single material

Piezoelectric materials are used in two ways. They serve as sensors for dynamic loads such as vibrations and impacts, and they can also harvest energy by converting mechanical movement into electrical energy. A piezoelectric sensor can therefore supply its own power. However, it only responds to changing loads. Piezoresistive materials respond to pressure with a measurable change in resistance, so they can also detect static loads precisely and sensitively. Until now, the two material types have usually been developed separately. The Chemnitz team combines both principles in one film only about 40 µm thick.

The two fillers divide the work between them. BaTiO₃ is a lead-free piezoceramic. It supports local polarization and promotes the formation of the electroactive phase of PVDF, which is responsible for the piezoelectric effect. The carbon nanotubes form an electrically conductive network in the polymer. When the film is compressed, the contacts between the nanotubes change and the electrical resistance changes with them. The nanotubes also reinforce the polymer mechanically.

“Our central question was how the ceramic and conductive fillers act together inside the PVDF matrix,” says Prof. Dr. Olfa Kanoun, head of the Professorship of Measurement and Sensor Technology at TU Chemnitz. “By adjusting both concentrations systematically, we could control the material structure and direct its performance toward energy conversion or pressure detection.”

PVDF is lightweight, flexible and suitable for large-area processing. To perform well as a piezoelectric material, however, it usually needs high-voltage electrical poling, mechanical stretching, or both. In the new composite, the fillers take over this task during film formation. The ceramic particles promote the polar crystal structure, and the nanotubes act as nuclei that increase the overall crystallinity of the polymer. At the interfaces between polymer, ceramic particles and nanotubes, microcapacitor-like regions form, which increase charge accumulation and polarization. As a result, the electroactive content of the films is up to about twice as high as in pure PVDF. Their piezoelectric coefficient reaches values comparable to those of electrically poled PVDF-based systems.

Simple processing produces flexible thin films

The films are produced by solution casting. PVDF and the fillers are dispersed in a solvent, then cast and thermally treated. The result is a homogeneous, flexible film. For energy-harvesting tests, the films were placed between flexible electrodes to form compact nanogenerators.

“A homogeneous distribution of the ceramic particles and carbon nanotubes was essential,” explains Dipl.-Ing. Ahmed Attaoui, lead author of the study. “The performance depends not only on the individual constituents, but also on the interfaces formed between them.”

The composition decides which effect dominates

The team succeeded to systematically vary the nanotube content at each ceramic level. This allowed them to link the composition of the material to its structure, mechanical strength, electrical output and pressure sensitivity. The composite is considerably stiffer and stronger than pure PVDF, yet it stays flexible.

A formulation with a higher nanotube content delivered the best energy harvesting. It reached output voltages of up to 25 V and a maximum power of 345 microwatts, about a hundred times more than the same material without nanotubes. The material also demonstrated long-term stability: The output voltage remained stable over 20,000 loading cycles. Even after 50,000 and 100,000 cycles, the peak voltage decreased only slightly, while the overall signal shape was preserved. A formulation with more ceramic and fewer nanotubes gave the highest pressure sensitivity, while still delivering a high electrical output. This formulation was therefore selected for all subsequent device tests.

“The important result is the controllability of the system,” says Kanoun. “One composition can be selected for higher electrical output, while another can be selected for pressure sensitivity. This gives device designers a clear basis for choosing the formulation that fits the intended function.”

“Combining piezoelectric and piezoresistive effects in one material opens up a range of possible uses, from sensors to energy harvesters and, in future, actuators,” says Kanoun. “Our results provide a materials basis for exploring these functions within one composite system.”

Toward self-powered smart skins and wearable electronics

A demonstration shows how the two effects complement each other in a single device. When the researchers pressed the film steadily with a fingertip, its electrical resistance dropped clearly while almost no voltage was generated. Rapid tapping, by contrast, produced strong voltage pulses. The same film can therefore register how strongly and how long it is pressed, and at the same time harvest energy from movement. The team also showed that the harvested energy is usable: The rectified output charged capacitors within a few seconds and powered an array of LEDs.

The concept is aimed at flexible and wearable electronics, where space, weight and energy supply are limited. Potential applications include self-powered pressure sensors, electronic skins, health-monitoring patches, robotic tactile interfaces, structural monitoring and autonomous Internet of Things devices.

The researchers are now investigating whether the material can also produce controlled mechanical motion under electrical excitation. This could extend the concept to actuation, for example vibrotactile feedback in wearable and interactive systems. “The study provides a materials basis for compact autonomous devices”, says Attaoui. “The next step is to translate the measured material properties into reliable components and to evaluate how energy harvesting, sensing and actuation can be integrated at device level.”

Interdisciplinary and international cooperation

The study is the result of a cooperation between the Professorship of Measurement and Sensor Technology and TU Chemnitz alumna Dr. Ayda Bouhamed. She is now at the Faculty of Sciences of Gafsa, University of Gafsa, and a member of the Laboratory of Electromechanical Systems at the National Engineering School of Sfax in Tunisia. The work was carried out during her visiting professorship at TU Chemnitz. The visiting professorship allowed the partners to combine their expertise in nanocomposite materials and sensor technology. It also strengthens the long-standing collaboration between TU Chemnitz and research institutions in Tunisia.

“It is a special pleasure for me to collaborate with my alma mater,” says Dr. Ayda Bouhamed. “The visiting professorship program gave us the opportunity to bring our expertise together in Chemnitz, and it shows how well scientific cooperation works across borders today.”

Further partners from TU Chemnitz contributed their expertise: Prof. Dr. Martin F.-X. Wagner and Mario Scholze from the Institute of Materials Science and Engineering, and Prof. Dr. Christoph Tegenkamp from the Professorship of Analysis of Solid Surfaces at the Institute of Physics. Prof. Dr. Chokri Bouraoui from the Laboratory of Mechanics at the National Engineering School of Sousse, University of Sousse, co-supervised the work. The cooperation brought together measurement and sensor technology, materials science and surface physics.

The Free State of Saxony is supporting structural transformation in Southwestern Saxony with further multi-million-euro investments in science and research. One of the largest planned investments is the construction of a new cleanroom for research and technology development in the field of sustainable microelectronics and sensor technology at the Center for Micro and Nanotechnologies (ZfM) at Chemnitz University of Technology. Unspent EU funds are to be utilized for the building, which will cost approximately €68 million. Subject to approval by the European Commission, this will enable the implementation of a project that strengthens Chemnitz University of Technology's research infrastructure and creates new opportunities for collaboration with research institutions and companies. This was announced by the Saxon State Ministry of Science, Culture and Tourism in a press release published on August 25, 2026.

“We are absolutely thrilled that, even in these highly constrained and challenging fiscal times, the construction of the new cleanroom for research and technology development in the field of sustainable microelectronics and sensor technology can be realized. This represents an exceptionally significant investment in Chemnitz University of Technology—particularly in its core competencies of materials and intelligent systems — as well as in the entire region of Southwestern Saxony. We would like to express our heartfelt thanks to the Saxon State Government — in particular to Minister-President Michael Kretschmer and Minister of Science Sebastian Gemkow — as well as to everyone else involved for their outstanding support!" says Prof. Dr. Gerd Strohmeier, Rector of Chemnitz University of Technology.

With the planned cleanroom, the ZfM will further expand its expertise in micro- and nanotechnologies. The focus will be on technologies for sustainable microelectronics and sensor technology. The new infrastructure creates the prerequisite for cutting-edge research and technology development, while also aiming to intensify collaboration with non-university research institutions and industry partners.

“The planned new cleanroom represents a milestone boost for the Center for Micro and Nanotechnologies at Chemnitz University of Technology. Through these forward-looking investments, our world-class research can be further expanded and strengthened. This state-of-the-art infrastructure serves as a tremendous source of motivation for our staff and acts as a magnet for leading international researchers. In doing so, we are not only creating optimal conditions for research into sustainable microelectronics and cutting-edge technologies in quantum computing, neuromorphic computing, photonics, and smart sensors, but we are also building a stronger bridge between excellent research and industrial applications. As a key player in the region, we make a significant contribution to value creation—from which regional partners will benefit in the long term," said Prof. Dr. Harald Kuhn, holder of the Professorship for Smart Systems Integration at the Faculty of Electrical Engineering and Information Technology at Chemnitz University of Technology, Director of the Fraunhofer Institute for Electronic Nano Systems (ENAS), and Director of the ZfM at Chemnitz University of Technology.

The planned investment is part of a comprehensive package of measures by the Free State of Saxony to strengthen Southwestern Saxony as a hub for science and research. This includes 79 European research funding projects (ERDF/JTF) in the field of mechanical and plant engineering, totaling more than € 80 million, as well as projects totaling over € 200 million in medium-term financial planning through 2031.

Background: The Center for Micro and Nanotechnologies (ZfM)

With the ZfM, Chemnitz University of Technology (TU Chemnitz) is home to one of the world’s leading research centers for microsystems technology and nanotechnologies. It represents one of the technological cornerstones of the Southwestern Saxony industrial region and serves as an indispensable pillar of Silicon Saxony. Key research areas include system miniaturization, energy efficiency, performance enhancement with reduced resource consumption, and the integration of micro- and nanoscale components into complex systems.

Microelectronics is the core enabling technology for AI, medical technology, autonomous systems, as well as energy and mobility solutions—forming the foundation of industrial transformation. With over 120 German and 49 European partners, the ZfM serves as a global development partner for industry. The planned new building is therefore far more than just a construction project; it is of immense strategic importance. Ultimately, it will help secure and expand more than 300 highly skilled jobs in Saxony.

In quantum computers, ions prefer to be isolated and kept at freezing temperatures because, to achieve optimal performance, they must be as isolated from their environment as possible. Only then can quantum operations be performed on them without perturbation. To this end, the ions are confined in a trap by electric fields, and the entire ion trap is cooled to a temperature of less than 10 Kelvin (just above absolute zero) in a high vacuum. Quantum computers based on such ion traps are currently attracting a great deal of interest in industry and science, particularly with regard to their miniaturization. This requires new concepts, materials, and technologies for heterogeneous system integration. This expertise is a strategic priority of the European Chips Act and will now be strengthened in Chemnitz and further developed for new areas of application. This is being carried out by Chemnitz University of Technology and the Chemnitz-based Fraunhofer Institute for Electronic Nano Systems (ENAS), in collaboration with partner institutes of the German Microelectronics Research Factory (FMD).

At the new “Cryo-Lab for Materials and Electronics Packaging Chemnitz”—CRYME for short—based at Chemnitz University of Technology, scientists aim to research and develop materials, components, and systems for future generations of quantum computers, as well as evaluate their reliability. Thanks to an investment project by Fraunhofer ENAS, funded by the Federal Ministry of Research, Technology, and Space (BMFTR), state-of-the-art equipment was acquired, including two specialized cooling devices known as cryostats, a cryogenic materials testing system for determining thermomechanical properties, and a cryogenic scanning electron microscope for materials analysis at extremely low temperatures. This technology is now jointly operated by Fraunhofer ENAS and Chemnitz University of Technology. As part of the European Test and Reliability Center (ETRC), CRYME strengthens the close collaboration between Fraunhofer ENAS and the FMD as well as the Chair of Materials and Reliability of Microtechnological Systems, the Center for Micro- and Nanotechnologies (ZfM), and the Research Center for Materials, Architectures, and Integration of Nanomembranes (MAIN) at Chemnitz University of Technology. The new laboratory is located at the Research Center MAIN. The new helium liquefaction plant at the neighboring Institute of Physics also plays an important role, as some of CRYME’s cryostats are powered by liquid helium.

“As a key technology of the 21st century, quantum computing also stands for technological leadership, high-quality jobs, and cutting-edge research. That is why the Chemnitz researchers involved in CRYME view the new laboratory as a key building block for innovation, new large-scale research projects, excellent teaching, and attracting young scientists,” says Prof. Dr. Bernhard Wunderle, holder of the Chair of Materials and Reliability of Microtechnical Systems. At the same time, he notes that the collaboration taking place here is a prime example of successful cooperation on the “Smart Systems Campus” in Chemnitz.

Dr. Remi Pantou, head of the “Characterization and Analytics” group at Fraunhofer ENAS and laboratory director of CRYME, adds: “CRYME’s new facilities are a key factor for collaborative projects with industry partners, as the complexity of this specialized research laboratory is unique in Germany and Europe. Several companies have expressed interest in collaborating. Specific collaborative projects have already begun, and additional projects are in the planning stages.”

The new laboratory will be officially opened on September 2, 2026, as part of a two-day event called “Chemnitz Seminars,” which will be held under the theme “Testing and Reliability Between Ice and Fire: New Laboratories and Methods from 4 K to 700 K.” The event covers topics related to testing and reliability and provides an ideal platform for sharing knowledge, discussing practical applications, and identifying future opportunities for collaboration within CRYME. Registration for the free seminar is open until August 21, 2026.

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.

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.

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.

Background: Across and the eCampus sub-project

The European University Alliance „Across – European University for Cross-Border Knowledge Sharing“, coordinated by TU Chemnitz, promotes the exchange of knowledge, skills, and resources across national and institutional borders. Through innovative cooperation in education, research, administration, and third mission activities, Across aims to strengthen international collaboration and the long-term visibility of its partner universities. Key activities include the development of joint teaching offers and the expansion of mobility opportunities for students and staff. The „Across eCampus“ is a TU Chemnitz-led sub-project and a central building block within the alliance. As a digital infrastructure, it is intended to systematically facilitate access to cross-institutional offers.

On December 22, 2015, the United Nations General Assembly adopted Resolution A/RES/70/212, establishing the International Day of Women and Girls in Science. Since then, the United Nations, UNESCO, intergovernmental organizations, and numerous institutions from science and civil society have highlighted every year the importance of recognition, participation, and visibility of women in research and science. Despite progress, gender equality remains a major global challenge. Promoting young women, ensuring access to high-quality education, and translating scientific knowledge into practice are key measures to achieve this goal.

At TU Chemnitz, supporting early-career female researchers, strengthening women in leadership positions, and enabling the reconciliation of family, studies, and academic careers are central concerns in an increasingly complex research and work environment. Against this backdrop, TU Chemnitz is aligning with the UN initiative for the third time.

In connection with International Women’s Day on March 8, TU Chemnitz invites female scientists of all career stages, female students and university staff to the 3rd International Women-in-Science Day on March 6, 2026, at the Altes Heizhaus, Straße der Nationen 62, Chemnitz. No registration is required.

Focus Topic: Women’s Health

The 2026 event focuses on women’s health and its relevance for scientific careers, workplace structures, and academic environments. The event provides a platform for interdisciplinary exchange, new perspectives, and the empowerment of women in science.

The hosts of the event are Prof. Dr. Anja Strobel, Vice-Rector for Research and University Development at TU Chemnitz, and Karla Kebsch, Equal Opportunities Officer of TU Chemnitz.

Scientific Lectures and Program

The event opens with a scientific lecture giving psychological perspectives on Menstruation and Mentrual Pain. Further lectures explore the influence of hormonal, physical, and neurological factors on women’s careers and provide practical insights into cycle-oriented nutrition and performance.

A networking break offers space for discussion. In the afternoon, the project TUC_FemAktiv will be officially launched.

The day concludes with “Coffee & Talk”, an informal exchange format in which female students and researchers can connect with the Vice-Rector and the Equal Opportunities Officer, share experiences, discuss research interests, and address individual needs in a relaxed atmosphere.
