Abstract

Soft pumps have the potential to transform industries including soft robotics, wearable devices, microfluidics and biomedical devices, but their efficiency and power supply limitations hinder prolonged operation. Here, we report a self-powered triboelectric-electrohydrodynamic pump, which combines a soft electrohydrodynamic pump driven by an electrostatic generator, specifically a triboelectric nanogenerator. The triboelectric nanogenerator collects ambient energy and converts it into high-voltage power source, allowing it to self-power an electrohydrodynamic pump and thus eliminating the need for external power supply. Using power management circuit, geometric shape optimization, and stacking methods, we achieve a maximum pressure of 4.49 kPa and a maximum flow rate of 502 mL/min. We demonstrate the pump's versatility in applications such as self-powered soft actuators, oil pumping in microfluidics, and oil purification. The triboelectric-electrohydrodynamic pump holds promising applications, and offers new insights for the development of fully self-powered systems.

摘要

柔性泵有潜力变革包括软体机器人技术、可穿戴设备、微流体和生物医学设备在内的诸多行业，但其效率和电源限制阻碍了长时间运行。在此，我们报告一种自供电摩擦电-电流体动力泵，它将由静电发生器（具体而言是摩擦纳米发电机）驱动的柔性电流体动力泵结合在一起。摩擦纳米发电机收集环境能量并将其转换为高压电源，使其能够为电流体动力泵自供电，从而无需外部电源。通过使用电源管理电路、几何形状优化和堆叠方法，我们实现了4.49千帕的最大压力和502毫升/分钟的最大流速。我们展示了该泵在自供电软体致动器、微流体中的油泵送以及油净化等应用中的多功能性。摩擦电-电流体动力泵具有广阔的应用前景，并为全自供电系统的发展提供了新的见解。
