At the interface between chemistry, physics and material science, we are interested in organic electronic and hybrid materials such as semiconducting and conducting polymers and organic small molecules and their application in electronic devices such as field-effect transistors and electrochemical transistors. Furthermore, we are investigating structure-property relationships and charge transport in these materials in conjunction with a variety of organic electronic and ionic applications such as flexible and stretchable (bio) sensors. Due to their printability, mechanical flexibility and low Young's modulus that is in compliance with biological tissues these devices offer the potential of revolutionizing personalized medicine and health monitoring.

 

Organic Field-Effect-Transistors

Organic electronic devices are of great potential for e.g. bendable displays and conformable sensor arrays due to their printability and mechanical flexibility.

 

Light-Responsive Electonic Devices

We study and improve fundamental device prerequisites and functionalize organic transistors with stimuli-responsive materials for sensing and memory applications.

 

Organic Bioelectronics

Their mixed electronic and ionic conduction makes organic electrochemical transistors (OECTs) ideal transducers of biological signals. We study the charge transport in and device functionalization of OECTs aiming for mobile electronic immunosensors with high sensitivity for point-of-care diagnostics.

 

Stretchable Electronics

The low elastic modulus of polymers matches that of soft biological tissues. We aim to develop soft and stretchable sensors for stretchable on-skin, health-monitoring sensors that could take personalized medicine to the next level. For this purpose, we study and develop stretchable conductive materials and devices.
