Outline of Final Research Achievements

This research was carried out on the basis of the unique characteristics of carbon nanotube (CNT) thin films, aiming to develop fundamental technologies to realize novel 3D electronics with innovative functionality and designability, As the results, all-CNT integrated circuits in which CNT thin films were used as not only transistor channel but also electrodes and interconnections were realized for the first time. The all-CNT ICs exhibit transparency and excellent flexibility. The 3D devices were realized by adapting thermo-forming technique to all-CNT device. Moreover, the evolutional research was carried out to develop wearable healthcare devices exploiting the excellent stretchability of CNT thin films. The all-CNT devices with excellent stretchability was realized on PDMS thin film. Flexible CNT biosensors with high sensitivity were also developed.
