Abstract:
1. A pump, comprising: a plurality of electroosmotic membranes comprising one or more positive electroosmotic membranes and one or more negative electroosmotic membranes; and a plurality of conductive polymer electrodes comprising one or more cathodes and one or more anodes; wherein the electrodes are store a chemical potential across the electroosmotic membranes sufficient to operate the pump in the absence of any externally applied electrical potential; wherein the positive electroosmotic membranes and negative electroosmotic membranes are disposed alternately to form a membrane stack; wherein at least one cathode is disposed on one side of one of the membranes and at least one anode is disposed on another side of that membrane and the at least one cathode and the at least one anode are operatively coupled to each other, and wherein at least one cathode or anode is disposed between a positive electroosmotic membrane and a negative electroosmotic membrane.
