• Transduction of smart hydrogel swelling state by advanced flexible CNT-based MEMS capacitors on a membrane platform (HydroMEMS) (DFG project 548242085): This project aims at exploring a novel miniaturizable and energy efficient transduction concept for smart hydrogels, i.e. polymers that exhibit a reversible and repeatable volume-phase transition in response to an external stimulus. The approach is based on self-forming flexible microstructures created by vertically aligned carbon nanotube (VACNT) pillar electrodes whose resistive/capacitive properties are altered by deformation induced swelling of the smart hydrogel.
• Electrically controlled processes on semiconductor-gas interfaces for power to fuel technologies (DFG project 527334504): This project explores semiconductor-based devices that use the electroadsorptive effect (EAE) to control gas adsorption on catalytic surfaces through low-voltage electrical signals. By integrating metal–insulator–semiconductor structures with oxide thin films, the work aims to electrically tune surface reaction kinetics and improve the efficiency of catalytic processes as a fundamental basis for future Power-to-Fuel technologies.
