报告摘要：

Electroosmotic pumps have been widely used in microfluidic systems. However, traditional HV-Source is bulk in size and induces numerous accessional reactions, which largely reduce the system’s portability and efficiency. Herein, we report a motion controlled, highly efficient micro-flow pump based on triboelectricity driven electroosmosis. Utilizing the triboelectric nanogenerator (TENG), a strong electric field can be formed between two electrodes in the micro-fluidic channel with electric double layer, thus drives the controllable electroosmotic flow by biomechanical movements. The advantages of economy, efficiency, portability and safety render TEOP a more conducive option to achieve wider applications in motion-activated micro/nano fluidic transportation and manipulation.
