About
Ryuji Sugiura is a leading researcher in the emerging field of safe human-robot interaction, with a specific focus on preventing soft tissue injuries from blunt impacts. His work is foundational to establishing safety criteria for the next generation of personal care and collaborative robots. Sugiura’s major contribution lies in systematically defining the mechanical thresholds—such as critical contact pressure and total transferred energy—that cause bruises. To achieve this, he pioneered the use of *in vivo* impact tests on anesthetized porcine specimens, a methodology that provides the most realistic data on human-like tissue tolerance. His highly cited 2017 paper (27 citations) established the dominant parameters for bruise tolerance, while his 2019 study (22 citations) revealed critical differences in injury susceptibility between the chest and extremities. Expanding beyond physical experiments, Sugiura has developed sophisticated finite element (FE) models of porcine and human limbs, enabling virtual crash testing for robot design. His 2025 FE analysis represents a significant leap, translating experimental thresholds into a computational tool for estimating human arm bruise tolerance. By bridging biomechanics and robotics, Sugiura is directly shaping the safety standards that will allow humans and robots to work and live together safely.
