Smart Sensors in action

The Professorship of Electrical Measurements and Sensor Technology presents its research on SENSOR+TEST

The Professorship of Electrical Measurements and Sensor Technology (MST) of the Chemnitz University of Technology presents application-specific sensors, autarkic sensor systems and embedded diagnosis of batteries solutions for intelligent sensors at the international sensor fair trade SENSOR+TEST in Nuremberg, from May 30, till June 1st, 2017. The researchers join the central German joint booth “Forschung für die Zukunft”. The booth with number 207 is located in Hall 5.

The appearance of the Chemnitz researchers on the world’s most important fair for sensor technology, measurement and testing technology serves to present on the one hand their research focus and on the other hand to further strengthen and expand the network to research institutes and businesses within and outside of Germany.

Applications in e-mobility and regenerative energies

The team around Prof. Kanoun also presents research results regarding the subject of impedance spectroscopy, meaning the determination of alternating current resistance, which allows the indirect determination of inaccessible measured parameters. This procedure enables the prediction and determination of the system’s stauts such as batteries. Aim is the fully automated online surveillance of individual cells up to big batteries, used for example in electric cars and the storage of regenerative energies. Sensors based on impedance spectroscopy give access to numerous measured parameters in only one measurement: “This expands the variety of application scenarios of impedance spectroscopy for example in the food industry, environment monitoring, and process technology”, explains Prof. Olfa Kanoun, Chair holder of Electrical Measurements and Sensor Technology.

The right sensor for every application

Furthermore, the Chemnitz researchers present flexible sensors for strains and pressures, adaptable to the respective measuring task. In order to realize this, the researchers integrated conductive carbon nano tubes (CNT) in a non-conductive plastic matrix. The strain and pressure sensors can be applied onto the measurement object via standard printing procedure.

International workshop in September

Together with the Instrumentation and Measurement Chapter of the Institute of Electrical and Electronics Engineers (IEEE) the research group of Prof. Kanoun will host the 10th international Workshop on impedance spectroscopy from September 27 till 29, 2017. Additionally, within the workshop an Advanced School on Impedance Spectroscopy will be offered. “The aim is to provide the junior researchers of this field with a better entry in specific topics of impedance spectroscopy and simultaneously strengthen their international connections”, says Kanoun. Because strong junior researchers will research for innovative solutions of the future.
