About

Ho Jung Lee is a leading innovator in the field of wearable electronics and self-powered sensor systems, with a primary focus on triboelectric nanogenerators for advanced tactile sensing. Dr. Lee’s most notable contribution is the development of a stretchable triboelectric pressure sensor featuring a hierarchical superposition pattern, which achieves exceptional strain insensitivity while maintaining high pressure sensitivity. This breakthrough, detailed in their highly cited 2021 paper (63 citations), addresses a critical challenge in artificial skin and soft robotics: decoupling pressure detection from mechanical deformation. By ingeniously combining polystyrene bead templating with micro-patterned structures, Lee’s design enables reliable, self-powered sensing even under stretching, bending, or twisting—a key requirement for next-generation prosthetics and human-machine interfaces. Their work has been instrumental in advancing the practicality of triboelectric sensors, bridging the gap between laboratory prototypes and real-world wearable applications. With a growing citation impact and a clear trajectory toward scalable, energy-autonomous sensing, Ho Jung Lee stands out as a rising authority in smart materials and flexible electronics, inspiring future research in self-powered artificial tactile systems.
