By utilizing Kyocera's proprietary ceramic piezoelectric element inside the head of the toothbrush, it turns electric signals into vibrations to transmit music directly to the user without the use of external speakers, so only the child can hear the music*.
Called Possi, the toothbrush uses ceramic piezoelectric element inside the head of the toothbrush which turns electric signals into vibrations to transmit music directly to the user without external speakers, the official release noted.
The Ultrasonic Thickness Gauge works by measuring the interval of a sound pulse generated by the ultrasonic transducer containing a piezoelectric element, which gets agitated by a short electric impulse causing a flare of ultrasonic waves inside the Ultrasonic Thickness Gauge to pass through the test piece and reflect back.
The subject of the research is the piezoelectric element of a linear piezoceramic motor, i.e.
Principal schemes of the piezoelectric element: 1--clamping area; 2--copper foil coated by composite PZT; 3--electrode
NES can absorb and dissipate energy through targeted energy transfers (TET) so that NES coupled with piezoelectric element could realize vibration control and energy harvesting.
Ultrasonic transducers based on piezoelectric materials are normally based on the excitation of geometrical resonances of the piezoelectric element. Although use of resonant devices improves sensitivity of the transducer it also has a negative impact on the frequency bandwidth, which is reduced, especially when compared with other non-resonant solutions (e.g.
The core of this microphone is a piezoelectric element impacted with sound waves (directly or through a membrane).
A sinusoidal electronic input in the radio frequency (RF) range creates a standing sound wave, which drives piezoelectric element vibrations.
The Zigbee PRO Green Power extension supports light switches that transmit a command using only the energy developed by flipping the switch--it's recovered by a piezoelectric element. (3)
Instrument electrode "Tweezer", made of rustfree sheet plate with screws to fix the piezoelectric element, is attached to a ceramic back-plate.
