Patent number: 8651630Abstract: In one embodiment, a fluid ejector structure includes: a chamber for containing a fluid; a flexible membrane forming one wall of the chamber; a plurality of piezoelectric elements; a backing operatively connected to the piezoelectric elements such that an expansion and/or contraction of a piezoelectric element causes the piezoelectric element to bend; a rigid plate overlaying a center portion of the membrane; a post coupling the piezoelectric elements to the plate through the backing such that a movement of each piezoelectric element toward the chamber is transmitted to the plate through the post. The plate is configured to transmit movement of the post to the membrane in a rigid, or substantially rigid, piston-like manner.Type: GrantFiled: January 20, 2009Date of Patent: February 18, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Adel Jilani, Tony S.

Publication number: 20130335487Abstract: A piezoelectric mechanism includes first and second electrodes and a thin film sheet of piezoelectric material. The second electrode is interdigitated in relation to the first electrode. The first and the second electrodes are embedded within the thin film sheet. The thin film sheet is polarized in a direction at least substantially perpendicular to a surface of the thin film sheet. The thin film sheet is to physically deform in a shear mode due to polarization of the thin film sheet at least substantially perpendicular to the surface of the thin film sheet, responsive to an electric field induced within the thin film sheet at least substantially parallel to the sheet via application of a voltage across the first and the second electrodes.Type: ApplicationFiled: April 5, 2011Publication date: December 19, 2013Inventors: Tony S.

Patent number: 8573747Abstract: An electrostatic liquid-ejection actuation mechanism includes a membrane, a frame, and one or more deformable beams. The frame has two sides and a number of cross members that are non-parallel to the two sides. The two sides and the cross members define one or more areas individually corresponding to one or more liquid chambers. The deformable beams are disposed between the membrane and the frame. The deformable beams individually correspond to the liquid chambers, and define a number of slits. Each slit is adjacent to one of the two sides of the frame. The deformable beams have a width that is less than a width of the liquid chambers, due at least to the slits.Type: GrantFiled: October 31, 2008Date of Patent: November 5, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Adel Jilani, Jun Zeng, Kenneth James Faase, Tony S.
