Nothing is impossible — Constantin Wiesener has proven this with an innovative idea from the field of medical technology. The 34-year-old from Potsdam took first place at this year's Speed Lecture Awards at the BIONNALE in Berlin. Within only three minutes he was able to convince the audience of his research work. His goal: to enable wheelchair users to move their legs, such as cycling or swimming, by means of targeted functional electrostimulation (FES). Wiesener studied electrical engineering and audio communication at the TU Berlin. After working as a software developer at zplane.development and Native Instruments and as a control engineer at Berlin Heart GmbH, he has now returned to the TU to work on his doctorate in the field of control systems.
