摘　　要：电液动力学(EHD)是研究在流体上施加电场后流体的流动。在微分析系统中,EHD的主要应用是电动泵(EKP)技术即电泳泵和电渗泵两个主要泵技术。这些独特的泵技术被广泛应用在推动极小截面的管道中化学和生物流体流动,管道尺寸从平方毫米到平方微米量级,甚至纳米通道量级。近年来,电渗泵出现了填充床、整体柱、平行多通道、纳米通道和微孔膜等各种新的形式,显示了其在微分析系统的集成化和在毛细管液相色谱、流动注射分析和药物输送等应用研究中的潜力。本文对电动泵技术进行了评述。Electrohydrodynamics （EHD） deals with the motion of fluids driven by an electric field applied to the fluids. The main application of EHD in microsystems is an electrokinetic pump （EKP） technique including two important types of EKP, electrophoretic pump （EPP） and electroosmotic pump （EOP）. These unique pump techniques are widely used to move chemical and biological fluids in channels with extremely small cross sections, ranging from square millimeters to square micrometers and even to nanochannel size. Recently, there are many fabrication techniques for various EOP such as packed-bed, polymer monoliths, parallel channel, nanochannel and microporous membrane pump, showing its integration in microsystems and promising applications such as capillary liquid chromatography, flow injection analysis and drag delivery. The microfabricate and related techniques of EKP are reviewed.
