  • Patent number: 11770657
    Abstract: A piezo-electric element includes a piezo-electric element part, a support part, and a stretchable film. The piezo-electric element part includes a piezo-electric film and electrodes between which the piezo-electric film is sandwiched in a thickness direction. The support part supports a peripheral portion of the piezo-electric element part. The stretchable film is provided in an oscillation region located inside of the peripheral portion of the piezo-electric element part. The stretchable film also has a higher elasticity than that of the piezo-electric element part.
    Type: Grant

  • Patent number: 10585191
    Abstract: An ultrasonic sensor in the invention includes an ultrasonic transmitter, an ultrasonic receiver, and a detector. The ultrasonic transmitter transmits pulse-shaped ultrasonic waves to a thin plate to excite the thin plate. The ultrasonic receiver receives direct waves and reflected waves among the ultrasonic waves propagating in the thin plate excited by the pulse-shaped ultrasonic waves, the direct waves propagating only in the thin plate, and the reflected waves radiating outward, then reflected by the object, and returning to the thin plate. The detector detects the object present near the thin plate on the basis of a difference between a time at which the ultrasonic receiver receives the direct waves and a time at which the ultrasonic receiver receives the reflected waves.
