About

Hao Chang is a leading researcher in the field of soft robotics and advanced materials, with a focus on liquid metals and ferrofluids. His work bridges the gap between magnetic control and non-magnetic materials, most notably through the development of a liquid gripper based on phase-transitional metallic ferrofluid. This innovation, published in 2021 and cited over 119 times, enables precise, real-time manipulation of non-magnetic objects—a breakthrough with significant implications for manufacturing, biomedical devices, and micro-robotics. Chang has also pioneered methods to imbue liquid-metal soft robots with vibrant, iridescent colors, transforming their appearance from silver-white to kaleidoscopic hues through thin-film interference and electrolysis. This work, cited 69 times, opens new avenues for aesthetic and functional design in soft robotics. Additionally, his research on the fast solidification of pure gallium at room temperature (12 citations) addresses the longstanding challenge of supercooling, enabling more reliable micromechanical properties for flexible electronics and thermal management. Together, Chang’s contributions are shaping the future of adaptive, multifunctional materials and systems.
