Hiroo Sekiya

About

Hiroo Sekiya is a leading researcher in wireless power transfer (WPT) and power electronics, with a particular focus on enabling untethered robotic systems. His major contributions center on the design and optimization of high-frequency, load-independent WPT systems that achieve constant output and soft switching without active control—a critical advancement for applications like articulated robot arms. Sekiya’s most cited work (50 citations) introduces a design procedure for load-independent class-E inverters, ensuring robust performance under varying loads. He has further pioneered the integration of WPT with wireless communication to create fully “wire-free” robotic joints, eliminating all wired connections. His research on 6.78 MHz WPT systems for robot arms, using class-E inverters and class-D rectifiers, demonstrates practical, analytically derived solutions for power delivery in constrained, moving environments. With a growing citation record and a clear trajectory toward practical, high-impact applications, Sekiya is shaping the future of autonomous, cable-free robotics.
