Electroosmotic pump and method of use thereof

An electroosmotic pump, comprising:

• a plurality membranes comprising positive electroosmotic membranes and negative electroosmotic membranes, wherein each of the positive electroosmotic membranes and negative electroosmotic membranes are disposed alternatively;
• a plurality of electrodes comprising cathodes and anodes, 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 other side of the membrane and wherein at least one of the cathodes or anodes is disposed between a positive electroosmotic membrane and negative electroosmotic membrane, and
• a power source to provide a voltage between about 0.1 to 25 volts, wherein the membranes and electrodes are operably coupled to the power source to generate a pressure of at least about 0.75 PSI.
