About

Sangjin Han is a leading researcher in the design and control of flexible robotic systems, with a particular focus on advancing robotic-assisted minimally invasive surgery (RMIS). His work bridges mechanical design and intelligent sensing, developing novel tools that can navigate confined anatomical spaces with unprecedented precision. Han’s most influential contribution is his work on analytical PID controller design, which has garnered 71 citations and provides a rigorous framework for tuning these ubiquitous control systems. In the realm of surgical robotics, he has pioneered the use of optoelectronic sensors for both contact force and shape sensing, as demonstrated in his highly cited 2019 paper on S-shaped beam sensors for flexible manipulators (30 citations). His innovative shape sensing approach, which uses optoelectronic sensors to measure the full curvature of a robotic arm, enables real-time feedback critical for safe, delicate procedures. Further extending his bio-inspired design philosophy, Han has developed a human finger-inspired grasping structure that integrates a tactile sensing array using a single type of optoelectronic sensor, simplifying sensor integration while maintaining high-fidelity force measurement. Through these contributions, Han is defining the next generation of dexterous, sensor-rich surgical tools.
