Abstract

Abstract: On the basis of the discussion for middle pressure-producing principle, the transfer characteristics for liquid in a new type of complex parallel, or series electroosmotic pump system was investigated. In a multi-series electroosmotic pump, the pressure of a pump can be elevated by increasing the progression of an electroosmotic pump or applied voltage. But it has disadvantage because of its limit in liquid transfer. In a multi parallel connection electroosmotic pump, the flux of a pump can also be elevated by increasing the progression of an electroosmotic pump or applied voltage. The system can be used in a wide range due to the fold of liquid flux. But it has disadvantage in controlling the operation condition because of its smaller linear range caused by Joule heat.

Key words: Electroosmotic pump, Pressure, Flow rate
