About

Xuezeng Zhao is a leading researcher in the fields of tactile perception, tribology, and robotic dynamics, with a focus on understanding how mechanical interactions—from fingertip friction to multibody systems—inform both human sensing and machine design. His most influential work, "Tactile Perception of Roughness and Hardness to Discriminate Materials by Friction-Induced Vibration" (2017, 46 citations), is a cornerstone in haptic science. In this study, Zhao demonstrated how the human fingertip, equipped with highly sensitive mechanoreceptors, decodes surface roughness and material hardness through skin vibrations generated during sliding contact. This work bridges biomechanics and materials science, offering a framework for designing biomimetic tactile sensors. More recently, Zhao has expanded into robotics with "Multibody Dynamics Modeling of Delta Robot with Experimental Validation" (2021, 5 citations), where he developed and validated dynamic models for high-speed parallel manipulators, advancing precision in automation. His contributions are pivotal for students and researchers exploring haptic interfaces, human-robot interaction, and friction-driven perception, establishing him as a key figure in translating tactile phenomena into engineering innovation.
