Researchers at Arizona State University's Flexible Display Center (FDC) and the University of Texas at Dallas (UT Dallas) have successfully produced CMOS circuitry on a flexible plastic substrate. Primarily designed to advance flexible electronics, the new plastic CMOS circuits have demonstrated exceptional power efficiency—one-third the power consumption of traditional thin film transistor circuitry. The new flexible CMOS is ideal for potential applications such as smart medical bandages or triage patches.
The research and development project has focused on integrating two types of thin film transistors—N-type amorphous silicon and P-type organic silicon—to fabricate CMOS logic gates on flexible polyethylene napthalate (PEN), a high-temperature polyester film. The electrical duality between the NMOS and PMOS transistors achieves dramatically reduced power consumption for flexible circuits.
