The potential uses of organic semiconductor devices are discussed. They will find use in wearable electronics, chemical sensors, skin for robots and innumerable other applications. A key advantage of organic transistors over silicon is their ease of fabrication. While building a silicon chip involves complex and expensive processes, organic transistors can be made using faster, cheaper processes under less carefully controlled conditions. The properties of the two broad types of conductive plastics, where one is made out of small organic molecules and the other out of long conjugated polymer molecules, are also discussed. The development of electronic skin for robots, which could give a robot a sense of touch, is also discussed.
