微流体装置，由于其方便的小尺寸和微尺度体积中流体的独特物理化学行为，已经成为许多科学和技术领域中的重要工具。微通道、微阀和微泵中的流体流动与通过微电子电路的导线、开关和电流源的电流有许多相似之处。然而，等效的可变电阻器仍然不可用。在这里，作者提出了可寻址的变形元件的微阵列产生十六个级别的流动阻力。使用纯电阻电路模拟，他们预测三入口混合器的稳态输出。(c)2006年，美国物理学会。
Microfluidic devices, due to their conveniently small size and the unique physicochemical behavior of fluids in microscale volumes, have become essential tools in many areas of science and technology. Fluid flow in microchannels, microvalves, and micropumps have many parallels with electrical current through wires, switches, and current sources of microelectronic circuits. The equivalent of a variable resistor, however, is still unavailable. Here the authors present addressable microarrays of deformable elements producing sixteen levels of flow resistance. Using a purely resistive electrical circuit analog, they predict the steady-state output of a three-inlet mixer. (c) 2006 American Institute of Physics.
