Electroosmotic pump

An electroosmotic pump (EOP) is a type of pump that utilizes electroosmosis to move fluids, primarily in microfluidic systems. The principle of electroosmosis involves the movement of a liquid through a porous medium or microchannel due to an applied electric field. This phenomenon occurs when an electric field is applied across a liquid that contains charged species—typically ions—resulting in the movement of liquid as the ions migrate.
