Research Projects

Organic Transistors	Application of printing methods in producing organic transistors has promised low-cost electronics, but a printed transistor has a poor performance due to the thick semiconductor layer. Also, most of organic transistors operate at high voltages (> 40V). We are investigating two types of organic transistors, OMESFET and dual gate transistor, to overcome the voltage problem and enhance the performance in a thick film transistor.
Carbon Nanotube Actuators	Using Carbon nanotubes as artificial muscles
Dielectric Elastomer Actuators	Using silicone rubbers as artificial muscles
Conducting polymer based active catheter for OCT imaging application	Place your abstract here...
