About
Manabu Aoyagi is a prominent researcher specializing in ultrasonic motor technology and acoustic propulsion systems, whose work bridges precision actuation and underwater robotics. His most significant contributions lie in the development of multidegree-of-freedom (MDOF) spherical ultrasonic motors (SUSMs), where he has pioneered innovative rotor and stator configurations — including rotor-embedded and outer-rotor designs — that enable compact, gearless actuation with high torque at low speeds. These qualities make his motors particularly attractive for robotic joints and manipulators, as demonstrated across multiple influential publications dating back to 2011, with his 2018 sandwich-type SUSM paper earning 24 citations and standing as his most recognized work. More recently, Aoyagi has expanded his research into acoustic underwater propulsion, exploring PZT disc and ring transducers, lithium niobate crystals, and surface acoustic wave (SAW) systems to drive miniature swimmers. His 2022 and 2023 papers on multi-degree-of-freedom acoustic swimmers have each garnered 16–17 citations, reflecting strong community interest. Across both research threads, Aoyagi demonstrates a consistent focus on harnessing piezoelectric phenomena to build efficient, compact actuators — making his work highly relevant to students and engineers working in robotics, biomedical devices, and underwater exploration technologies.
