About

Hee Won Seo is a leading researcher in the field of soft robotics and smart materials, with a particular focus on the development of advanced artificial muscle actuators. His most notable contribution is the pioneering work on electrically controllable twisted-coiled artificial muscle actuators (TCAs), where he demonstrated that surface-modified polyester fibers—specifically polyethylene terephthalate (PET) yarns—can achieve remarkable linear actuation of up to 8.9% when thermally activated. This breakthrough, published in 2017 and cited over 60 times, opened new pathways for creating lightweight, flexible, and electrically controllable actuators for use in prosthetics, wearable devices, and soft robotic systems. By combining material science with practical engineering, Seo’s work addresses key challenges in actuator performance, including controllability and energy efficiency. His research continues to influence the design of next-generation bio-inspired robots and smart textiles, making him a key figure in the rapidly evolving landscape of soft actuation technologies.
