Research on Large-Scale Organic Circuits with Flexibility and Transparency
Wearable and implantable devices are expected to be used for long-term applications for early detection and treatment of diseases, and must exhibit extremely minimal "mechanical flexibility" to biological tissues. In this research, we develop electronic devices based on printed circuit boards that exhibit excellent elasticity and transparency, and by constructing technologies for integrating organic semiconductors and transistor circuits, we move forward toward the realization of flexible electronics with built-in large-scale organic circuits. In particular, the aim of this research is to stabilize changes in electrical characteristics due to internal factors, which has been an issue up to now.


Aiming not only to create new device properties, but also to advance to flexible electronics and create value with them.

Outline of Research Achievments

In this research, we carried out research and development on electronic devices based on printed wiring boards, which have excellent elasticity and transparency, and obtained knowledge to stabilize electrical characteristics. We not only discovered materials and structures that stabilize electronic devices against fluctuations of internal and external factors, but also realized a sheet-type sensor that incorporates a large-scale organic transistor circuit. Since the sheet-type sensor has excellent bending and stretching properties, there are high expectations for its application in next-generation medical devices that are safe for living organisms.
