Research Interests

Interactive electronic devices by soft nanomaterials

Nano-sized electronic materials, such as metal nanowires, conjugated polymers, and carbon nanotubes, have a high flexibility that traditional electronic materials like silicon lack. These soft nano-electronic materials enable electronic devices that are highly compatible with soft human tissue, such as computer interfaces that integrate with the skin, and healthcare sensors that can accurately measure biological signals over a long time. We develop novel soft materials, evaluate devices, and explore novel applications, with the aim of creating interactive electronics that seamlessly integrate into our daily lives.

The followings are the major research topics in our group:

Soft and stretchable electronic materials.
Stretchable semiconductor devices.
Development of novel sensors using soft electronic materials.
Development of novel displays using soft electronic materials.
Exploration of novel applications (wearable devices, human-computer interfaces, biological measurements, etc.)

A printable stretchable conductor. The material demonstrates high conductivity even when stretched to five times its original length.
A wireless soft sensor and display system consisting of a stretchable high-frequency diode, liquid-metal antenna, carbon nanotube sensor, and conducting polymer display.
An ultrasoft display integrated with the skin.
