Devices, systems and methods according to the present invention utilize electrokinetic pumps capable of generating high and low pressures flow for various medical applications, including drug delivery and analyte sampling. The EK pumps and systems are configured and constructed to be low cost, compact and precise. In one embodiment, the EK pump comprises a first fluid reservoir 102 and a second fluid reservoir 104. First fluid reservoir 102 is coupled to second fluid reservoir 104 by through- vias 106, 110 and porous dielectric material 108. Through-vias 106 and 110, along with porous dielectric material 108 proivde a fluidic path between first reservoir 102 and second reservoir 104. Each fluid rservoir further comprises a fluid port 118, which can be an inlet or outlet, and capacitive electrode 120a and 120b. |
