We demonstrate control of fluid motion in three-dimensional structures with thousands of microchannels. Fluids are manipulated via an electrocapillary pressure, originating from electrostatic control of the solid/fluid interfacial tension in the microchannels. Reversible fluid displacement has been achieved for all channel orientations with respect to gravity. The velocities of several centimeters per second are nearly two orders of magnitude higher than the velocities demonstrated by other electrofluidic actuation principles.
我们展示了对具有数千个微通道的三维结构中流体运动的控制。流体通过电毛细管压力进行操控，该压力源于对微通道中固/液界面张力的静电控制。对于所有相对于重力的通道方向，都实现了可逆的流体位移。每秒几厘米的速度比其他电流体驱动原理所展示的速度高出近两个数量级。
