Paper Abstract

A novel micro-machined valveless diffuser-nozzle micropump is presented in the present paper. The micropump is designed by thermally bubble driven actuation method. This pumping mechanism requires no mechanical moving parts for actuation and control of inlet and outlet. As a result, it requires substantially simplified fabrication process in two wafers, which is compatible with IC fabrication processes. The proposed micropump will provide high actuation stroke than existing micropumps.
