Abstract: Processes for forming an actuator having a curved piezoelectric membrane are disclosed. The processes utilize a profile-transferring substrate having a curved surface surrounded by a planar surface to form the curved piezoelectric membrane. The piezoelectric material used for the piezoelectric actuator is deposited on at least the curved surface of the profile-transferring substrate before the profile-transferring substrate is removed from the underside of the curved piezoelectric membrane. The resulting curved piezoelectric membrane includes grain structures that are columnar and aligned, and all or substantially all of the columnar grains are locally perpendicular to the curved surface of the piezoelectric membrane.

Abstract: An ink jet printhead includes: a nozzle plate having an underside and including one or more nozzles in the underside configured to dispense drops of fluid in a dispensing direction; and a multi-level maintenance structure coupled to the nozzle plate such that a gap exists between a portion of the maintenance structure and the underside of the nozzle plate. The maintenance structure includes: a first portion having a first upper surface suspended at a first distance from the underside of the nozzle plate; and a second portion that is coupled to the first portion, the second portion having a second upper surface suspended at a second distance from the underside of the nozzle plate, which is greater than the first distance, the second upper surface laterally displaced relative to the first upper surface.

Abstract: An inkjet device includes a pumping chamber bounded by a wall, a piezoelectric layer disposed above the pumping chamber, a ring electrode having an annular lower portion disposed on the piezoelectric layer. A moisture barrier layer covers a remainder of the piezoelectric layer over the pumping chamber that is not covered by the annular lower portion of the ring electrode.
