摘 要:
介绍了基于电流变液控制的微流芯片的工作原理和制作过程，由于电流变液的粘度随外加电场的增加而增大，且这种改变是可逆的，响应时间也极快（毫秒量级）。利用此特性，作者设计制成了电流变液数值型微流阀。基于此类微流阀，作者制成了一系列微流器件，例如：微流混合装置、微减震器以及微流泵。[著者文摘]

Abstract:
We report the design and fabrication of microfluidic chips based on the electrorheological （ER） fluid mechanism. An ER fluid has a viscosity that increases as the applied field strength increases, is reversible, and has a fast response time on the order of 1-10 ms, making it an ideal material for microfluidic valves with digitally-control characteristics. With such a valve we have successfully fabricated a series of microfluidic devices, such as a microfluidic mixer, micro-damper and micro-pump.[著者文摘]
