About

Takumi Hirata is an emerging researcher specializing in acoustic underwater propulsion systems, with a particular focus on ultrasonic transducer-based technologies for miniature robotic swimmers. His work centers on developing innovative propulsion mechanisms that harness acoustic driving forces generated at solid-liquid interfaces, offering a compelling alternative to conventional mechanical propulsion systems such as fins or screws. This approach eliminates moving parts, significantly reducing mechanical complexity while opening new possibilities for miniaturized underwater robotics. Hirata's most impactful contribution, "Acoustic underwater propulsion system based on ultrasonic disc PZT transducer" (2023), has garnered 17 citations, establishing him as a notable voice in the field. His subsequent investigation into 36° Y-cut lithium niobate transducers demonstrates a systematic effort to optimize material selection and transducer design for enhanced propulsion performance, with related works accumulating an additional 12 citations across two publications. By exploring both PZT and lithium niobate piezoelectric materials, Hirata brings valuable comparative insight into transducer performance for self-propelled acoustic robots. Though early in his career, his focused and technically rigorous body of work positions him as a promising contributor to the rapidly advancing field of acoustic micro-robotics and underwater autonomous systems.
