Outline of Final Research Achievements

Recently, developments of flexible devices which can be placed on cloths and skins have been studied to reduce discomfort during wearing these wearable devices. Meanwhile, the printing technology have been an important technology for a fabrication of electronic devices to realize large area and cost efficiency. In our study, integration technologies between stretchable conductors and organic transistors and it's peripheral technologies were developed with printing technologies. For example, conductors with high-stretchability and atmospheric stability, substrates integrated with rigid and soft materials, circuit designs for bio-signal sensing, etc.
