About

Kohei Motoo is a researcher in tactile sensing and mechanical resonator design, with a focus on developing robust, self-sensing force sensors. His most notable contribution is the invention of a novel tactile sensor that uses a vibrating piezoelectric element, detailed in his 2006 paper "Novel Force Sensor Using Vibrating Piezoelectric Element." This work introduced a sensor capable of measuring elastic deformation in media under external force, with adjustable sensitivity and sensing range—a significant advancement for applications requiring durable, self-sensing capabilities. The sensor's design, based on a piezoelectric bimorph, eliminates the need for separate excitation and detection components, enhancing reliability. With 7 citations, this paper has influenced subsequent research in resonator-based tactile sensors. Motoo's work stands out for its practical approach to force measurement, offering a solution that balances robustness with precision. His contributions are particularly relevant for robotics and haptic interfaces, where adaptable and resilient sensing is critical. By integrating mechanical resonance with piezoelectric principles, Motoo has advanced the field of tactile sensor technology, providing a foundation for future innovations in smart materials and adaptive sensing systems.
