Abstract:
A method of fabricating a multilayer ceramic micropump device including the steps of:providing a plurality of ceramic layers; forming into the plurality of ceramic layers a plurality of channels and cavities in microfluidic communication to define upon completion of the device a first ball check valve and a second ball check valve in microfluidic communication; placing within the first ball check valve a first ball and within the second ball check valve a second ball; laminating each of the plurality of ceramic layers having the first ball and the second ball positioned therein, to form a ceramic monolithic package; sintering the monolithic package to form a functional monolithic three-dimensional micropump device defining therein the first ball check valve including a moveable first cofired ball, and a second ballcheck valve including a moveable second cofired ball.
