Abstract
The present invention relates to microfluidic devices, and in particular, flow management in such devices. In particular, the present invention provides an electrostatic valve for flow manipulation in a microfluidic device. The valve of the present invention sits on a valve seat in a microchannel and deflects away from the valve seat by electrostatic actuation to assume an opened configuration to allow fluid flow.
