About

Osamu Tsutsumi is a materials scientist and engineer whose research sits at the intersection of flexible electronics, soft materials, and advanced sensing technologies. His work focuses on developing next-generation sensors capable of measuring mechanical deformation in soft and biological systems, with particular emphasis on liquid crystal-based optical sensing and wearable robotics applications. Tsutsumi's most influential contribution is his comprehensive review of flexible multifunctional sensors for wearable and robotic applications, which has amassed over 323 citations since its 2019 publication — a testament to the field's rapid growth and the work's role as a foundational reference. This review synthesized cutting-edge developments in high-sensitivity, mechanically flexible sensors, helping to define research priorities for an entire community of engineers and scientists. Beyond review scholarship, Tsutsumi has pioneered innovative approaches to three-dimensional strain measurement using cholesteric liquid crystal sensors applied to silicone elastomers — a critical capability for soft robotics development. His investigations into the mechano-optical response of chiral liquid-crystalline elastomers further demonstrate his commitment to engineering materials whose optical properties respond intelligently to mechanical stimuli. Together, these contributions position Tsutsumi as an emerging voice in soft matter sensing and flexible device research.
