Welcome to the website of the Donghee Son Laboratory in Electronic and Electrical Engineering at Sungkyunkwan University

 Our research group seeks to achieve an unprecedented bio-integrated electronic system that is able to bridge the undesired gap between approaches of materials science and medicine, combining applications of soft and/or self-healing materials to high-performance flexible/stretchable devices with translational biomedical engineering efforts.

 Our research group focuses on the two kinds of soft bio-integrated electronic systems: Self-healing and stretchable artificial skin systems and neural devices. We hope that these works are a valuable stepping stone which brings qualitative improvement to our society.
