Flexible Devices Group
The "Flexible Devices" group was founded in 2019 and has a strong research focus on flexible sensors and electronics. With regard to trends such as the Internet of Things and Industry 4.0, the target applications include geometry-adaptive adhesive tapes, medical technology and wearables through to robot skin.
In addition to investigating suitable substrate materials, the working group focuses on the development of suitable technologies to realize electronic and sensor components on these flexible substrates. This requires the application and structuring of suitable electrical conductors using various processes such as PVD and CVD deposition, patterning based on lithographic and wet chemical processes, as well as additive technologies such as printing processes.
The goals are to improve the performance of these components, to make production more efficient in terms of resources and costs, and to open up new areas of application.

M. Sc. Franz Selbmann
Franz Selbmann completed his studies in electronic and sensor materials at Freiberg University of Mining and Technology in 2015 with a master's thesis in the field of parylene encapsulation at the Fraunhofer Institute for Electronic Nanosystems ENAS. After a research stay at Tohoku University in Sendai, Japan, in 2016, where he focused on the development of polymer-based MEMS, he began his doctoral thesis on the development of parylene as a material for microsystems and flexible devices in close collaboration with the Fraunhofer Institute for Electronic Nanosystems ENAS in Chemnitz. Since 2019, he is Head of the "Flexible Devices" group at the Institute for Nanoscale and Bio-based Materials at TU Freiberg. His research interests are in the field of advanced materials and integration technologies for intelligent systems and their applications.
