Abstract: Carbon nanotube thin films are promising electronic materials for flexible and stretchable devices with excellent wearability and performance because of the high-carrier mobility, mechanical flexibility, and biocompatibility. Recent progresses of CNT technologies such as high-purity separation processes enable us to realize the complex integrated circuits necessary for functional flexible devices such as wearable healthcare devices, electronic skin of robots, and so on. In the presentation, after reviewing recent progresses of carbon nanotube-based electron devices, our recent works on flexible integrated circuits and biosensors for wearable devices are presented. A concept to design carbon nanotube-based analog integrated circuits, which are indispensable for sensor devices, is presented, with a demonstration of the first carbon nanotube differential amplifiers on a flexible plastic film. Biosensing application of carbon nanotubes is also presented. The fundamental electrochemical activities of single-walled CNTs have been investigated to realize ultra-sensitive and selective detection of dopamine, a kind of neurotransmitters.
