Ambient electronics with organic transistors

We have developed large-area, flexible pressure sensors and actuators using organic transistor active matrices. The new sheet-type devices include electronic artificial skins and sheet-type wireless power transmission system in the manufacturing processes, printing technologies such as inkjet and screen printing systems are employed. Thus, these large-area devices are potentially inexpensive to manufacture. Such a large-area feature of organic transistors is complementary to silicon-based conventional electronics that are high-performance, but expensive. The combination of silicon and organic electronics will be one of the key technologies in the forthcoming ambient electronics era.
