Abstract

Electrokinetic devices, including electrokinetic pumps, include a conduit and first and second electrodes adjacent to respective ends of the conduit. The electrodes together constitute a capacitive electrode pair. The electrodes can be composed of double layer capacitive materials, for example carbon-based materials, or pseudocapacitive materials. The devices can operate without producing chemical change in the electrolyte solution.
