Patent ID: 7086839

Claim:
An electroosmotic pump comprising: a. at least one porous structure for pumping fluid therethrough and having an average pore size, the porous structure having a first side and a second side and having a first continuous layer of electrically conductive porous material having a first thickness along an axis parallel to an overall direction of fluid flow disposed on the first side, wherein the first thickness is less than the average pore size and a second continuous layer of electrically conductive porous material having a second thickness along the axis parallel to the overall direction of fluid flow disposed on the second side, wherein the second thickness is less than the average pore size, wherein at least a portion of the porous structure is configured to channel flow therethrough; and b. means for providing electrical voltage to the first layer and the second layer to produce an electrical field therebetween, wherein the means for providing is coupled to the first layer and the second layer.
