ABSTRACT:
A dielectric gate and related systems and methods for controlling fluid flow. A dielectric gate includes one or more electrodes coupled between an inlet fluid pathway and an outlet fluid pathway. The electrodes are configured to draw fluid from the inlet fluid pathway to the outlet fluid pathway in a precise manner by using dielectric forces arising from electrical signals applied to the electrodes.
