Abstract:
1. A flow controller, comprising: (a) a channel having (b) a fluid contained within said channel; (c) spaced electrodes in electrical communication with said fluid; (d) a power supply in electrical communication with said electrodes for applying an electric potential to said spaced electrodes; (e) a first node between the fluid inlet and the porous dielectric material; (f) a first flow element having a first flow element inlet in liquid communication at the first node at pressure PN with said fluid inlet and said fluid source, wherein P (g) at least one sensor for monitoring at least one control signal; and (h) a feedback control mechanism operatively connected to the sensor and the power supply; whereby the feedback control mechanism maintains the at least one control signal within a predetermined range by modulating the electric potential applied by the power supply.
