About

Hanbin Choi is pioneering the frontier of soft, intelligent materials that blur the line between synthetic systems and living tissue. His core research focuses on iontronic elastomers and bio-inspired artificial sensory neurons, creating materials that can sense, heal, and actuate—much like human skin. Choi’s most notable contribution is the development of an ultrafast, underwater self-healing piezo-ionic elastomer (83 citations), which autonomously repairs mechanical damage while simultaneously sensing pressure, a breakthrough for aquatic soft robotics and waterproof electronics. He also introduced the concept of ion trap and release dynamics (iTRD) to create a monolithic artificial tactile nerve (53 citations), overcoming the limitations of weak tactile memory in conventional systems. This work enables nonintrusive tactile augmentation, a key step toward lifelike prosthetics. Additionally, his ions-silica percolated dielectric elastomer actuator (27 citations) resolves the longstanding trade-off between force and strain in soft actuators. By integrating self-healing, sensing, and actuation into single-material platforms, Choi is redefining what soft robots and human-machine interfaces can achieve in challenging, real-world environments.
