电动气动泵（EPP）是一种轻型、灵活的静电泵，它使用介电液体放大拉链机构来控制空气量和压力，并产生高空气流量。在以前的研究中，EPP，矩形绝缘电极制成，能够充气/放气气动执行器和低功率软泵操作。本文探讨了EPP电极的一系列设计，以增加压力产生，空气传输和流速。结果，新的EPP能够产生12.24 kPa的最大压力，或11.25 kPa的压差，与之前的研究相比，提高了481%。在最大可用体积的18%处的额外液体电介质使EPP能够获得最大EPP性能。EPP的新设计是通过结合两个相同的拉链区域和最小化非活动区域而开发的。不同的致动器尺寸和致动频率进行了研究。该泵能够在0.4瓦的低功耗下在大气压下输送238 ml/min的最大流速（提高48%），并且它可以在高达4.47 kPa的压力下工作。据发现，拉链区域的形状和集成的柔性弹簧的行为显著影响装置的性能。最后，对EPP泵的进一步改进进行了探讨。
The Electro-pneumatic Pump (EPP) is a lightweight, flexible electrostatic pump that uses a dielectric-liquidamplified zipping mechanism to control air volume and pressure and generate high air flow rate. In previous studies, the EPP, made of rectangular insulated electrodes, was capable of inflating/deflating pneumatic actuators and operating as a low power soft pump. This article explores a range of designs for the EPP electrodes to increase pressure generation, air transference and flow rate. As a result, the new EPP was able to generate a maximum pressure of 12.24 kPa, or a pressure difference of 11.25 kPa, corresponding to 481% improvement from the previous study. Additional liquid dielectric at 18% of the maximum available volume enabled the EPP to attain maximum EPP performance. The new design of the EPP was developed by combining two identical zipping regions and minimising the inactive region. Different actuator dimensions and actuation frequencies were investigated. The pump was capable of delivering a maximum flow rate of 238 ml/min at atmospheric pressure (48% improvement) at low power consumption of 0.4 Watt, and it could operate up to 4.47 kPa. It was found that the shape of the zipping region and the behaviour of the integrated compliant spring significantly influences the performance of the device. Lastly, approaches to further improve the EPP pump are discussed.
