Ultra-flexible Electronics

Abstract

Flexible electronics are much attracted to next-generation electronics because of their features such as softness and flexibility. Recently, to utilize the softness of the electronics, the development of bio medical application is of particular interest.In this research, I will introduce various ultra-flexible electronics fabricated on an ultra-thin substrate with a thickness of about 1 micro-meter. The ultra-flexible electronics have extremely high flexibility, so that the device characteristics do not degrade even when the radius of curvature is reduced to 10 micro-meter. Furthermore, we can realize the stretchable electronics by integrating the device with stretchable substrate. By directly attaching the ultra-flexible devices to the skin, we succeeded in sensing biological information such as pulse, blood oxygen concentration, electrocardiogram, and electromyogram.
