About

Yang Cai is a pioneering researcher in the field of haptic perception for minimally invasive surgery (MIS), with a particular focus on restoring the critical sense of touch in laparoscopic and robotic procedures. His work addresses a fundamental challenge in modern surgery: when visual feedback is limited and natural haptic force feedback is distorted or absent, surgeons lose essential tactile information. Cai’s major contribution lies in developing artificial tissue models and haptic rendering techniques that translate physical forces into visual cues—such as forced tissue deformation—thereby providing surgeons with intuitive, real-time feedback. His 2024 paper, “Haptic Perception with Artificial Tissues,” has already garnered attention for its innovative approach to bridging the sensory gap in MIS. By enabling surgeons to “see” what they cannot feel, Cai’s research directly improves surgical precision and patient safety. His work stands at the intersection of biomedical engineering, robotics, and human-computer interaction, offering practical solutions that could transform training and practice in robotic surgery. For students and researchers, Cai’s contributions exemplify how creative engineering can solve real-world clinical problems.
