Abstract: Disclosed is a transducer incorporating a piezoelectric device for converting physical forces into an electrical signal. A high input impedance, low output impedance voltage operated amplifying device, preferably in the form of a P-channel enhancement MOS transistor, is combined with the piezoelectric element and supplied over a conventional single coax or two-wire cable from a remote power supply. The MOS transistor may be connected to the coaxial cable through a junction transistor.

Abstract: An optical module includes a translucent body, a vibrator that is tubular and supports the translucent body, a piezoelectric element located at the vibrator to vibrate the vibrator, and an inner-layer optical component at an inner side portion of the vibrator. The inner-layer optical component includes an inner-layer lens that faces the translucent body, a recess that is recessed in a thickness direction of the inner-layer lens and includes a curvature on a surface of the inner-layer lens facing the translucent body, and a gap is located between the translucent body and the recess of the inner-layer lens.

Abstract: A vibration device is provided that includes a vibration element with a piezoelectric vibrator and a driving device that causes the vibration element to vibrate. The vibration element includes a translucent body and the piezoelectric vibrator is electrically coupled to the driving device. The driving device includes a first circuit that applies an electric signal to the piezoelectric vibrator to render the vibration element in a resonant state, a second circuit that applies an electric signal to the piezoelectric vibrator according to a feedback signal output from the piezoelectric vibrator, and a switch that switches coupling between the first circuit and the piezoelectric vibrator and coupling between the second circuit and the piezoelectric vibrator at a certain timing.

Abstract: Aspects of this disclosure relate to driving a capacitive micromachined ultrasonic transducer (CMUT) with a pulse train of unipolar pulses. The CMUT may be electrically excited with a pulse train of unipolar pulses such that the CMUT operates in a continuous wave mode. In some embodiments, the CMUT may have a contoured electrode.
