Applications of microfluidics require a self-contained, active pumping system in which the package size is comparable to the volume of fluid being transported. Over the past decade, several systems have been developed to address this issue, but either these systems have high power requirements or the microfabrication is too complex to be cost efficient. A recent effort at Lincoln Laboratory using an emerging technology called electrowetting has led to the development of several novel micropump concepts for pumping liquids continuously, as well as for pumping discrete volumes.
