  • Piezoelectric actuator having a moveable electrode portion
    Patent number: 8890392
    Abstract: A piezoelectric actuator that includes a fixed electrode in a base substrate, a dielectric layer on the surface of the base substrate, a lower electrode that is at least partially separated from the base substrate, a piezoelectric layer on the surface of the lower electrode, and an upper electrode on the side of the surface of the piezoelectric layer. At least a portion of the upper electrode or the lower electrode serves as a movable electrode, which can be moved by distortion of the piezoelectric layer caused by application of a piezoelectric drive voltage.
    Type: Grant
    Filed: October 22, 2012
    Date of Patent: November 18, 2014
    Assignee: Murata Manufacturing Co., Ltd.
    Inventors: Kansho Yamamoto, Teiji Yamamoto, Ivo P. Koutsaroff
