About
Hocheol Gwac is pioneering the intersection of soft robotics and wearable sensor technology, with a focus on bioinspired materials for aquatic and human-interactive devices. His key research areas include stimuli-responsive hydrogels, carbon nanotube (CNT) yarn-based actuators, and multifunctional electronic skin (E-skin) systems. Gwac’s major contributions include the development of a poly(N-isopropylacrylamide) hydrogel for diving and surfacing devices, enabling micro aquatic robots to achieve three-dimensional locomotion without traditional motors—a breakthrough for remote sensing and search-and-rescue applications. He also created a self-powered multidirectional strain sensor using coiled CNT yarns, advancing E-skin capabilities for health monitoring and robotics. His work on wearable multi-plied potentiometric sensors, functioning as an electronic tongue, allows robots to detect taste and assess water quality or food freshness. Most recently, Gwac has developed multifunctional CNT and nylon hybrid fibers for thermal artificial muscles that operate without bias voltage, integrating self-sensing for enhanced control. With over 30 citations across his most-cited papers, Gwac’s innovations are shaping the future of autonomous underwater vehicles, intelligent prosthetics, and environmental monitoring.
