About
Dewei Lai is a leading researcher in the field of medical robotics and optical sensing, with a primary focus on developing miniature, high-sensitivity force and torque sensors for surgical applications. His work addresses critical challenges in minimally invasive procedures and robotic manipulation, particularly for intravascular and multi-finger robotic systems. Lai’s major contributions include the invention of an optic fiber-based torque sensor that employs a torsion-translation conversion flexure, achieving exceptional sensitivity for use in minimally invasive surgery robots—a paper that has garnered 18 citations. He also pioneered a proximal force/torque sensor for intravascular robots, featuring decoupled force and torque detection and an adjustable measurement range, with 15 citations. These innovations leverage Fiber Bragg Grating (FBG) elements and ortho-planar spring designs to enable precise, real-time feedback in constrained environments. Lai’s work is notable for its direct impact on enhancing the safety and dexterity of surgical robots, with his sensors offering a unique combination of miniaturization, high sensitivity, and mechanical simplicity. His research continues to push the boundaries of haptic feedback in robotic surgery, making him a key figure in advancing next-generation medical devices.
