About
Dr. Junghwan Chang is a leading researcher in electromagnetic energy harvesting, precision robotics, and advanced linear actuation systems. His most impactful work centers on developing self-powered systems for critical infrastructure, exemplified by his design of a novel electromagnetic energy harvester to power deicing robots and monitoring sensors for transmission lines (38 citations). He further advanced this field with nonlinear modeling and performance testing of a high-power electromagnetic energy harvesting system for a transmission line vibration deicing robot (33 citations). In robotics, Dr. Chang introduced a high-resolution optical encoder with an axially stacked coded disk for modular joints (24 citations), a breakthrough enabling compact, lightweight robotic arms. His contributions extend to contactless power transfer systems combined with linear electric machines, and he has developed sophisticated mathematical models to predict thrust ripple in flux-modulated linear actuators for five-axis gantry robots. With over 100 total citations, Dr. Chang’s work is pivotal for advancing autonomous robots in energy, agriculture, and industrial automation, demonstrating a consistent focus on integrating energy harvesting with precision motion control.
