About

Jaehyung Hong is a prominent researcher in the field of flexible and stretchable electronics, with a particular focus on electronic skins (e-skins) and biomimetic sensing technologies. His work has significantly advanced the development of piezoresistive composite elastomers, drawing inspiration from the intricate microstructures found in human skin to engineer sensors capable of detecting complex, multidirectional mechanical stimuli with exceptional sensitivity. Hong's most celebrated contribution, published in 2014, introduced interlocked microdome arrays that produce a giant tunneling piezoresistance effect, enabling ultrasensitive and multimodal electronic skins with transformative applications in healthcare monitoring, robotics, and prosthetics — a paper that has amassed nearly 900 citations. His concurrent work on tactile-direction-sensitive, stretchable e-skins, drawing directly from epidermal-dermal ridge architectures in human skin, has garnered over 630 citations, cementing his influence in the field. Later research further refined these designs by demonstrating tunable force sensitivity and selectivity through microstructure engineering. With well over 1,700 combined citations across these key works alone, Hong's contributions represent foundational advances in wearable sensing technology and human-machine interface systems.
