Profile
The research field of the Hong's group in Seoul National University covers fabrication, analysis, and application of thin-film devices, sensors, circuits, and integrated systems with flexible and stretchable forms. The recent aim of this group focuses on developing technologies for highly integrated and high-performance stretchable electronic systems using versatile printing techniques. This enables fully printable, system-level soft electronics for practical data processing and computing with advanced capabilities of universal circuit design and multilayer device integration. This design and integration tool provides a new layout of skin/bio-interfacing applications and further extends an applicable field of stretchable electronics.
