About

Jeong-Hoi Koo is a pioneering researcher at the intersection of biomedical engineering and smart actuator systems. His primary research areas include haptic feedback technologies, biomedical pulse simulation, and shape memory alloy (SMA) actuation. Koo’s most impactful contribution is the development of a compact pulsatile simulator using a cam-follower mechanism, which generates realistic radial pulse waveforms for cardiovascular research and medical training—a work cited 53 times. He further advanced haptic interfaces by designing a slim actuator based on electrorheological fluid, achieving 47 citations for its potential in virtual reality and robotics. In earlier work, Koo demonstrated nonlinear control of SMA-actuated robotic arms, earning 32 citations for stabilizing lightweight positioning systems. His recent efforts include a transfer function model for reconstructing arterial pulse pressures from non-invasive measurements, enhancing tonometry accuracy. Koo’s innovations bridge mechanical design and biomedical application, offering cost-effective solutions for pulse simulation and tactile feedback. His work is widely recognized for its practical impact on medical diagnostics and human-machine interaction, making him a notable figure in smart materials and bio-inspired robotics.
