A method of actuating a valve, comprises operatively coupling the valve with an electroosmotic pump; flowing a fluid through the electroosmotic pump; and generating a fluidic pressure of at least 0.75 PSI to actuate the valve, wherein the electroosmotic pump comprises one or more thin, porous, positive electroosmotic membranes and one or more thin porous, negative electroosmotic membranes; a plurality of electrodes comprising cathodes and anodes, and a power source; wherein each of the positive and negative electroosmotic membranes are disposed alternatively and wherein at least one of the cathodes is disposed on one side of one of the membranes and at least one of the anodes is disposed on the other side of the membrane and wherein at least one of the cathodes or anodes is disposed between a positive and a negative electroosmotic membrane. |
