Abstract
A fluid delivery system includes a first chamber, a second chamber, and a third chamber, a pair of electrodes, a porous dielectric material, an electrokinetic fluid, and a flexible member including a gel between two diaphragms. The pair of electrodes is between the first chamber and the second chamber. The porous dielectric material is between the electrodes. The electrokinetic fluid is configured to flow through the porous dielectric material between the first and second chambers when a voltage is applied across the pair of electrodes. The flexible member fluidically separates the second chamber from the third chamber and is configured to deform into the third chamber when the electrokinetic fluid flows form the first chamber into the second chamber.
