About
Tsutomu Tawa is a researcher whose work sits at the intersection of materials science, optics, and robotics, with a particular focus on developing advanced tactile sensing technologies. His primary research areas include photoelastic polymers, polyurethane synthesis, and the application of these materials in robotic tactile sensors. Tawa’s major contribution lies in elucidating the relationship between the photoelasticity of polyurethane and the dielectric anisotropy of diisocyanate, demonstrating that the elasto-optical constant is governed by the concentration and anisotropy of diisocyanate groups. This foundational insight, published in his most-cited 2020 paper (16 citations), enabled the design of high-photoelasticity polyurethanes. Building on this, his 2021 work (4 citations) showcased a practical application: a gripping sensor capable of detecting forces as small as 0.1–10 N using polyurethane with a photoelastic constant of 1000–10,000 ×10⁻¹² Pa⁻¹. By translating fundamental polymer physics into functional sensor prototypes for robot hands, Tawa bridges the gap between material innovation and real-world robotic manipulation, offering a compelling path toward more sensitive and intuitive tactile feedback systems.
