Hirohisa Tamagawa

About

Hirohisa Tamagawa is a leading researcher in soft robotics and bio-inspired actuation, specializing in the development of flexible, conductive composites and advanced control systems for artificial muscles. His work centers on ionic polymer-metal composites (IPMCs) and dielectric elastomer actuators (DEAs), aiming to replace rigid conventional actuators with lightweight, silent, and compliant alternatives for miniature robots, biomedical devices, and human-interactive technologies. Tamagawa’s major contributions include pioneering self-sensing control of Nafion-based IPMC actuators in extremely low humidity environments—a critical step toward practical, durable artificial muscles. He also advanced the fabrication of conductive and flexible multi-walled carbon nanotube/polydimethylsiloxane (MWCNT/PDMS) composites using a naphthalene/toluene mixture, achieving enhanced conductivity and flexibility for wearable electronics. His application of linear-quadratic regulator (LQR) control to conical DEAs further demonstrates his commitment to precise, biomimetic motion. With his most-cited paper garnering 17 citations, Tamagawa’s work is foundational for researchers exploring soft, muscle-like actuators. His innovative materials and control strategies continue to shape the future of soft robotics and human-safe automation.
