摘要：

从电动力学的角度提出了一种新的偶极直流电渗场效应控制方法。在薄层近似和低压极限下建立数学模型，验证偶极直流流动场效应晶体管结构在微米尺度进行流体电动操纵的可行性。采用两组并排反极性栅电极对的集成器件设计，建立了一种用于全电动驱动分析物处理的微器件模型，通过使用较小的栅极电压便可获得液体混合物，从而在小Dukhin数下产生较少的不利影响。该项技术在现代微流控系统中开发全自动液相执行器等方面具有应用价值。

Abstract:

A new method of bipolar field-effect control on DC electroosmosis（DCEO） is proposed from the perspective of electrodynamics. A mathematical model is established in thin-layer approximation and low-voltage limit to verify the feasibility of the bipolar DC-FFET structure for fluid electrodynamic manipulation at the micrometer scale. An integrated device design with two sets of side-by-side reverse polarity gate electrode pairs was used to construct a micro-device model for fully electrically driven analyte processing. By using a smaller gate voltage， an almost perfect liquid mixture can be obtained， resulting in less adverse effects at a small Dukhin number. This technology has great potential in the development of fully automatic liquid phase actuators in modern microfluidic systems.

Key words: microelectronics and solid-state electronics, bipolar DC field-effect flow control, flow field-effect-transistor, induced-charge electroosmosis
