  • High intensity focused ultrasonic piezoelectric actuator and method of manufacturing the same
    Patent number: 10584067
    Abstract: Disclosed is a focused ultrasonic piezoelectric actuator having a novel type of piezoelectric device for focusing ultrasonic waves. The focused ultrasonic piezoelectric actuator includes a dome-shaped piezoelectric body for focusing ultrasonic waves and a rim configured to facilitate focusing of ultrasonic waves of the body and injection of the dome-shaped piezoelectric body during a powder injection molding process, remove warpage of the dome-shaped body during a sintering process, and reinforce focusing intensity of the ultrasonic waves. The rim is integrally formed with the body. Accordingly, in the focused ultrasonic piezoelectric actuator, a dome-shaped focused ultrasonic piezoelectric actuator for focusing ultrasonic waves using a thickness vibration mode at a MHz frequency band is easily manufactured by a powder injection molding method, and thus an ultrasonic focusing effect is maximized.
