Instead of applying ointment and attaching a bandage, a “smart patch that regulates treatment intensity on its own just by being attached” has appeared. It is expected to develop into an intelligent treatment technology where light regulates drug release according to the patient’s condition in the future.

The team, led by Professor Kyung Cheol Choi of the School of Electrical Engineering, together with Dr. Daekyung Sung of the Korea Institute of Ceramic Engineering and Technology and Professor Chan-Su Park’s team at Chungbuk National University, has developed a self-regulating wound healing patch technology that combines organic light-emitting diodes (OLED) and a drug delivery system (DDS).
