About

Yijun Niu is a researcher specializing in rehabilitation robotics, wearable exoskeleton design, and biomechanical modeling, with a particular focus on bridging human kinematics with robotic systems to improve therapeutic outcomes. His most impactful work addresses one of the central challenges in exoskeleton design: the misalignment between the instantaneous center of rotation of human joints and their robotic counterparts. His 2018 paper on kinematic analysis and optimization of a planar parallel compliant mechanism for self-aligning knee exoskeletons has garnered 26 citations, establishing him as a contributor to safer, more comfortable wearable rehabilitation devices. Complementing this, his design of a planar compliant five-bar mechanism further advances practical solutions to reduce uncontrollable interface forces that can compromise user safety. Niu has also broadened his scope to upper-limb rehabilitation, developing a novel skeleton model and motion rhythm analysis framework for the human shoulder complex, demonstrating his versatility across the musculoskeletal system. Collectively, his work reflects a commitment to human-centered robotic design, making rehabilitation technology more anatomically compatible and clinically viable for individuals recovering from motor dysfunction.
