IMPROVEMENTS IN AND RELATING TO ELECTROOSMOTIC PUMPS

摘要

An electroosmotic pump comprises a plurality of membranes comprising one or more positive electroosmotic membranes and one or more negative electroosmotic membranes, a plurality of electrodes comprising cathodes and anodes, and a power source. Each of the positive electroosmotic membranes and negative electroosmotic membranes are disposed alternately 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 other side of the membrane. At least one of the cathodes or anodes is disposed between a postive electroosmotic membrane and negative electroosmotic membrane. The pump can be used to actuate a valve, or can be precharged, duch that an external power source is not required.
