ABSTRACT:
An electroosmotic micropump having a plurality of thin, closely-spaced, approximately planar, transversel aligned partitions formed in or on a substrate, among which electroosmotic flow (EOF) is generated. Electrodes are located within enclosed inlet and outlet manifolds on either side of the partition array. Inlet and outlet ports enable fluid to be pumped into and through the micropump and through an external friction load or head. Insulating layer coatings on the formed substrate limit substrate leakage current during pumping operation.
