Flexible and Nanobio Device Lab
















      FAND research goal is to develop 'Self-powered Flexible Electronic Systems'. This technology could provide interesting opportunities for printable electronics such as flexible displays, artificial skins, self-powered system, and biomedical applications for human machine integration. First, our laboratory is involved in self-powered systems such as sensor and nanogenerator for not only the mobile electronics but also convirting the tiny movements of human into electricity. Second, our studies  are also interested in laser material interaction such as excimer, solid state laser, and Flash lamp for the flexible applications.

      Third, we want to develop flexible inorganic micro LED (e.g. f-GaN or GaAs) for future display, invivo optogenetics and healthcare  applications. Finally, research aim is to develop flexible LSI (large scale integration ) for ultra-thin flexible CPU/high-density memory and novel electronics for neuromorphic computing.

   - Self-powered Sensors & Flexible Energy Source

   - Flexible Large Scale Integration and Memory for Neuromorphic Computing

   - Flexible Inorganic Micro LED for Display & Biomedical Applications

   - Laser Material Interaction for Flexible Applications
