About

Xuefei Leng is a researcher specializing in microfluidics and piezoelectric actuation, with a particular focus on innovative pump designs for fluid transport. Their most-cited work, "A spiral-tube-type valveless piezoelectric pump with gyroscopic effect" (2014), has garnered 18 citations and represents a key contribution to the field. This paper introduces a novel valveless pump that leverages the gyroscopic effect within a spiral tube structure, enabling efficient fluid flow without moving parts—a significant advancement for applications in medical devices, microelectronics cooling, and lab-on-a-chip systems. By eliminating valves, Leng’s design reduces wear and simplifies fabrication, addressing longstanding challenges in miniaturized pumping. This work underscores their expertise in combining piezoelectric materials with fluid dynamics to create robust, low-maintenance solutions. While their citation count reflects a focused, emerging impact, the conceptual novelty of the spiral-tube approach has inspired further studies in valveless pump optimization. Leng’s research bridges engineering and applied physics, offering practical pathways for precise fluid control in constrained environments. Their contributions are particularly valuable for students and researchers exploring non-traditional actuation mechanisms in microfluidics.
