研究の背景 Background


New electronic devices (electronics) that are lightweight, thin, and durable when bent or stretched are being developed using thin polymeric substrates. Flexible/stretchable electronics have various advantages; they can be applied to numerous locations; large-area electronics can be rolled up for transport, and they are break-resistant if dropped. In particular, we have entered the era of the Internet of Things (IoT), and various types of electronic sensor with a high cost efficiency (low cost for a large area) are demanded to collect information in the real world. Also in this sense, flexile, stretchable electronics fabricated by printing technology have been attracting attention.

研究の目標 Outcome


The latest developments in flexible, stretchable electronics using organic functional materials such as organic semiconductors have been studied. Our research group has succeeded in developing ultrathin organic electronic systems, which are light, thin, flexible, and stretchable. The ultrathin flexible electronics and their future prospect such as the contribution of such devices to the next generation of tools in the fields of medicine, health, and welfare have been developed.
