精确控制流体的泵送是微流体装置中的关键部件之一。从微流体技术发展的早期阶段起，电场就被用作最流行、最有效的非机械泵送机制之一，用于在微通道中输送流体。这篇综述介绍了由于在流体中施加电场而产生的不同微尺度现象的基本物理和理论，这些微尺度现象可以应用于微器件中的流体泵送。在本报告中考虑的具体机制是电渗，AC电渗，AC电渗透，诱导电荷电渗，行波介电泳和液体介电泳。每一种现象进行了系统的讨论与理论的严谨性和相关的关键参数的作用，确定在微型器件中的泵浦。我们具体讨论了电场驱动的体力项的每一个现象，使用广义麦克斯韦应力张量以及简化的有效偶极矩为基础的方法。本文着重介绍了几位研究人员对每种电场驱动泵浦机制的实验和理论研究。这些现象和相关的关键参数的详细理解是至关重要的，更好地利用，调制和选择适当的现象，在特定的微流体应用中的有效泵送。
Pumping of fluids with precise control is one of the key components in a microfluidic device. The electric field has been used as one of the most popular and efficient nonmechanical pumping mechanism to transport fluids in microchannels from the very early stage of microfluidic technology development. This review presents fundamental physics and theories of the different microscale phenomena that arise due to the application of an electric field in fluids, which can be applied for pumping of fluids in microdevices. Specific mechanisms considered in this report are electroosmosis, AC electroosmosis, AC electrothermal, induced charge electroosmosis, traveling wave dielectrophoresis, and liquid dielectrophoresis. Each phenomenon is discussed systematically with theoretical rigor and role of relevant key parameters are identified for pumping in microdevices. We specifically discussed the electric field driven body force term for each phenomenon using generalized Maxwell stress tensor as well as simplified effective dipole moment based method. Both experimental and theoretical works by several researchers are highlighted in this article for each electric field driven pumping mechanism. The detailed understanding of these phenomena and relevant key parameters are critical for better utilization, modulation, and selection of appropriate phenomenon for efficient pumping in a specific microfluidic application.
