About

Qi-Hui Zhang has pioneered the development of submillimeter-scale multimaterial terrestrial robots, a breakthrough field at the intersection of micro-robotics and biomedical engineering. Their most-cited work (136 citations) demonstrates how to construct robots smaller than a grain of rice using multiple materials, overcoming fundamental challenges in fabrication and locomotion at microscopic scales. This innovation opens transformative possibilities for minimally invasive surgical tools capable of navigating delicate tissues, as well as biological research vehicles that can manipulate individual cells. Zhang's contributions address the critical limitation of material constraints in micro-robotics, enabling more complex and functional designs than previously possible. Their research has been recognized for advancing the practical feasibility of medical microrobots, with potential applications ranging from targeted drug delivery to microsurgery. By bridging materials science, robotics, and clinical medicine, Zhang is establishing a new paradigm for how tiny machines can interact with biological environments, making them a leading figure in the rapidly growing field of submillimeter robotics.
