About

Iku Hamamoto’s research focuses on the development of flexible, wearable sensing technologies for robotics and biomedical applications, particularly in nursing care and rehabilitation. His major contribution is the invention of a string-type flexible displacement sensor (FDS) that can measure movement in both human bodies and robotic joints. This sensor, composed of fixed and slide electrodes with a nylon core, is designed to be soft, adaptable, and capable of tracking bending and displacement—critical for power-assisted devices and wearable health monitors. Although his most-cited works (2008–2009) have modest citation counts (2–4 each), they represent early, foundational efforts in flexible sensing, a field that has since grown explosively. Hamamoto’s work anticipated the current demand for unobtrusive, body-compatible sensors in medical robotics and assistive technology. His research is notable for bridging the gap between rigid conventional sensors and the need for compliant, human-friendly interfaces, making him a pioneer in the development of practical, low-cost wearable displacement sensors for rehabilitation and human-robot interaction.
