Our lab, can fabricate ultrathin devices, utilizing few micron-thick devices. It is lighter than feather and can be freely deformed without electrical failure due to their thinness. This unique technique is very compatible with skin electronics or implantable electronics and since it does not cause uncomfortable feeling to the users.

Combination of stretchable conductor and textile can make smart wearable devices such as strain sensor, bio-electrode and interconnection between E-skin sensors and measurement devices. Conductive, adhesive & printable ink is very promising material for realizing wearable smart devices.

In order to increase bio-compatibility of electronics, gas & liquid permeation is very important either on skin or implantable devices. Very recently we developed breathable electronics utilizing nanofiber substrate. As a result, sweat & oxygen or bio liquid circulation does not hindered during long term measurement for many applications.
