About

Xuehang Bai is a rising innovator in soft robotics and functional fluid actuation, whose work is redefining the boundaries of compliant, untethered machines. Bai’s primary research focuses on electrohydrodynamic (EHD) pumps and fluid-driven mechanisms, aiming to replace bulky, rigid actuators with silent, lightweight, and flexible alternatives. In a landmark 2024 study, Bai pioneered a novel soft robotic finger driven entirely by an embedded EHD pump, demonstrating how electrical input can be directly translated into controlled mechanical bending—a breakthrough that has already garnered 21 citations for its elegant modeling of voltage-to-geometry relationships. Complementing this, Bai’s design of a ring-shaped robot actuated by functional fluid (12 citations) tackles the longstanding challenge of simplifying mobile robot locomotion. By eliminating complex valves and external pumps, this work introduces a streamlined, self-contained rolling platform that moves through controlled fluid displacement. Bai’s contributions are notable for bridging fundamental fluid dynamics with practical robotic design, offering a clear path toward quieter, safer, and more adaptable soft machines. For students and researchers, Bai’s trajectory exemplifies how mastering the physics of smart fluids can unlock entirely new classes of bio-inspired, autonomous robots.
