Combined electroosmotic and pressure driven flow system

摘要

Electroosmotic flow controllers that may be used in conjunction with multiple fluids and methods of fluid flow control are described. The invention uses an electroosmotically generated flow component in combination with a pressure driven flow component to modulate fluid flow. A working fluid and a second fluid that supports electroosmotic function may be used in conjunction with embodiments of the invention. Embodiments of the invention may include salt bridges for making electrical connections between a power supply and a channel filled with a porous dielectric material and a fluid.
