Bio-inspired Optoelectronics
Research Goal
Our research group aims at developing next-generation electronic/ optoelectronic devices using functional nanomaterials (2D materials, silicon nanomembrane) and flexible/stretchable devices.
Our first goal is developing neuromorphic optoelectronic devices by employing interesting properties of functional nanomaterials and applying bio-inspired strategies.
Our second goal is developing neuromorphic sensory system based on flexible/stretchable devices for ubiquitous healthcare.
