ABSTRACT:
A micromachined fluid ejector includes an ejector body having a fluid cavity for holding fluid to be ejected and a piezoelectric actuator for ejecting the fluid. A nozzle plate is placed in operable association with the ejector body. The configuration of the nozzle plate is selected to adjust a volume of the fluid cavity to obtain a desired mechanical impedance matching between the fluid and the actuator.
