The team of Prof. Dr. Andreas Schütze at the Lab for Measurement Technology targets focuses on measurements of and with microstructures.

One focus is gas measurement systems, in particular the intelligent evaluation of multi-dimensional data structures of sensor arrays and virtual multi-sensors, i.e. dynamically operated, individual sensors, as well as the complex calibration of the sensor systems that is absolutely necessary for achieving high performance. The methodological solutions are tested, e.g. in the field of Green Buildings, e.g. for optimized ventilation to balance air quality and energy consumption, but also in safety applications and odor evaluation.

Our second focus, located in the research group Data Engineering and Smart Sensors at ZeMA, is targeting AI for industrial process control and condition monitoring. Here, methods of machine learning, in particular pattern recognition, are applied, often directly using process sensors, to determine the system status as a basis for service on demand, but also for process integrated quality control. In our projects, we primarily deal with the question of how to get the intelligence into the sensor, i.e. with distributed AI or edge computing, in which the first stage of signal evaluation and evaluation takes place directly within the smart sensor.

A third focus is addressing outreach activities and Public Understanding of Science and Humanities (PUSH). We want to support young talents especially demonstrating the fascination of hightech solutions. We use the "technical senses", the sensors, to bring schoolchildren closer to the latest technology, primarily through the school laboratory SinnTec and the high school student internship IngFo.
