Research Summary

Our research group is mostly focusing on developing soft electronic devices based on organic semiconductors. Soft (flexible/stretchable) electronics are highly demanded a wide range of applications that cannot be easily achieved from traditional rigid/brittle electronics such as e-skin, wearable electronics, bio-implantable devices, nerve interfaces, advanced healthcare system, etc. We mainly focus on developing novel soft materials by understanding the chemistry of materials for the facile fabrication process unlike the complicated process required for the stretchability of intrinsically non-stretchable materials. Besides, we are spending much effort into pursuing the realization of various deformable electronics and innovative applications through interdisciplinary studies.
