Patent number: 10478857Abstract: An ultrasonic piezoelectric transducer device includes a transducer array consisting of an array of vibrating elements, and a base to which the array of vibrating elements in the transducer array are attached. The base include integrated electrical interconnects for carrying driving signals and sensed signals between the vibrating elements and an external control circuit. The base can be an ASIC wafer that includes integrated circuitry for controlling the driving and processing the sensed signals. The interconnects and control circuits in the base fit substantially within an area below the array of multiple vibrating elements.Type: GrantFiled: June 20, 2018Date of Patent: November 19, 2019Assignee: FUJIFILM Dimatix, Inc.Inventors: Andreas Bibl, Hung-fai Stephen Law, Kevin von Essen, Mats G.

Patent number: 9362484Abstract: 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.Type: GrantFiled: February 23, 2015Date of Patent: June 7, 2016Assignee: FUJIFILM CorporationInventors: Paul A. Hoisington, Jeffrey Birkmeyer, Andreas Bibl, Mats G. Ottosson, Gregory De Brabander, Zhenfang Chen, Mark Nepomnishy, Shinya Sugimoto
