About

Hyeong Jun Kim is a rising innovator in the fields of stretchable electronics, soft robotics, and ion-based sensing technologies. His research focuses on harnessing the unique properties of mobile ions to create next-generation devices that are both flexible and self-powered. Kim’s most notable contribution is a groundbreaking method for stretchable and self-powered temperature sensing, published in 2022, which has already garnered 38 citations. This work demonstrates a novel three-layer structure—comprising an electrolyte, a dielectric, and an electrode—that enables temperature detection without an external power source, a critical step toward realizing the Internet of Everything. In 2024, Kim advanced the field of soft robotics with his work on electrostatic clutches based on ionomer heterojunctions, achieving low-voltage switching of stiffness and strength. This innovation overcomes the high-voltage limitations of conventional dielectric-based clutches, making them safer and more practical for haptic and robotic applications. With a citation count already reflecting the impact of his early-career work, Kim is establishing himself as a key figure in the development of intelligent, adaptive materials and devices for wearable technology and human-machine interfaces.
