ABSTRACT:
A pumping method is used for pumping a fluid from an inlet to an outlet of a pump having a plurality of micromechanical valves. Each micromechanical valve is for communicating a fluid and constructed from n-type and p-type materials forming a peltier junction interface which can be selectively cooled to freeze the fluid into a plug to obstruct the flow of fluid, or selectively heated to melt the plug to communicate the fluid in a tube extending through the junctions. A plurality of valves connected in series can be used together as a pump to pump the fluid from the inlet through the valves to the outlet. Selective heating and cooling of the junctions provides varying fluid pressures and plugs along the tube to pump the fluid through the tube.
