”The projects we have at IMMS are not only important to support companies with innovations. Rather, we work on solutions from which our society can benefit. That motivates me immensely because I want to contribute to a better society.”
”After my master’s thesis ’Development of core assemblies for a universal UHF RFID transmitter and 4-channel receiver‘ with Professor Ludwig Niebel at the Ernst-Abbe-Hochschule Jena, University of Applied Sciences, I got in touch with Eric Schäfer from IMMS. I knew IMMS from my on-the-job supervisor Professor Johannes Trabert. Eric was very interested in the RFID topic of my thesis and introduced me to the institute and the projects. There were many interesting questions about RFID transponders and ultra-low-power applications that I wanted to research there. In the official job interview, I could then get to know my future colleagues and could well imagine working at IMMS: We immediately started discussing contactless data transmission, far-field communications and especially RFID, and it was like a brainstorming session for new research and development work. Since then, I have been involved in a project that is all about RFID. The goal is to build integrated sensor systems that use extremely little energy and can thus be used to develop battery-free RFID sensor transponder systems. This will enable many applications in IoT and Industry 4.0, where many small sensors are to be used and not maintained.
I have been at IMMS since the beginning of 2020 and my work focuses on the application and verification of mixed-signal ASICs, especially for RFID transponders. There, I have developed a test setup for battery-free RFID sensor transponder systems. This can be used to test and characterise our passive UHF RFID transponders together with commercial, often power-hungry sensors. These findings have been incorporated into the new chip developments for passive UHF RFID sensor applications. It is very exciting to be able to contribute to completely new and very sophisticated solutions.
I really enjoy working here in a team where you can openly discuss and exchange your ideas. This and the flat hierarchies are a great pleasure for me and I like to think about the next working day. Not only that! The projects we have at IMMS are not only important to support companies with innovations. Rather, we work on solutions from which our society can benefit. That motivates me immensely because I want to contribute to a better society.“
