About

Takuya Sasatani is a pioneering researcher at the intersection of wireless power transfer (WPT) and soft robotics, dedicated to solving one of the field's most persistent challenges: how to untether flexible, continuum robotic systems without compromising their inherent mechanical advantages. His most influential work, "Continuum Robotic Caterpillar with Wirelessly Powered Shape Memory Alloy Actuators" (2020, 38 citations), demonstrated a breakthrough approach to integrating WPT with soft-bodied robots, enabling limitless operational time while preserving fluid, cable-free movement. Recognizing that rigid receiver coils fundamentally constrain continuum deformation, Sasatani developed innovative solutions that allow power delivery to conform alongside the robot itself. His research extends into dielectric elastomer actuation and advanced magnetic field management, including a novel Halbach array-based resonator design that significantly reduces harmful leakage magnetic fields — a critical barrier to deploying WPT in everyday environments like electric vehicles and industrial settings. Collectively, his work addresses both the practical safety and mechanical freedom necessary to bring wirelessly powered soft robotics into real-world applications, making him a notable emerging voice in the robotics and electromagnetic systems communities.
