Printed organic transistors: Toward ambient electronics

In the forthcoming ambient electronics era, multiple electronic objects are scattered on walls, ceilings or in imaginative locations and interact each other to enhance safety, security and convenience. For implementation of many electronic objects in our daily life, large-area, flexible devices, which would be printed on plastic sheet, cloth, and/or paper, are expected to play an important role. In this paper, we describe recent progress and future prospects of flexible, large-area electronics based on printed organic transistors.
