As society continues to age, the importance of personalized health care continues to grow. Consequently, interest is growing in wearable medical devices capable of real-time health monitoring and immediate treatment. However, existing wearable devices typically provide either biometric signal detection or drug delivery, with limitations in integrating multiple functions into a thin and stable structure.

To overcome these limitations, Professor Kyung-In Jang’s team designed a smart patch that integrates electrical and optical biometric signal sensors, a drug delivery system, and a wireless communication module into a foldable structure. This patch can automatically deliver drugs based on real-time biometric signals, enabling personalized treatment tailored to the user’s health condition(s).
