  2. Piezoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_sensor

    A piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated) A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo-is Greek for 'press' or 'squeeze'. [1]

  3. Piezoelectric accelerometer - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_accelerometer

    The cross-section of a piezoelectric accelerometer. The word piezoelectric finds its roots in the Greek word piezein, which means to squeeze or press. When a physical force is exerted on the accelerometer, the seismic mass loads the piezoelectric element according to Newton's second law of motion (=). The force exerted on the piezoelectric ...

    en.wikipedia.org/wiki/Piezoelectricity

    Piezoelectric balance presented by Pierre Curie to Lord Kelvin, Hunterian Museum, Glasgow. Piezoelectricity (/ ˌ p iː z oʊ-, ˌ p iː t s oʊ-, p aɪ ˌ iː z oʊ-/, US: / p i ˌ eɪ z oʊ-, p i ˌ eɪ t s oʊ-/) [1] is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in ...

  5. Integrated Electronics Piezo-Electric - Wikipedia

    en.wikipedia.org/wiki/Integrated_Electronics...

    The electronics of the IEPE sensor (typically implemented as FET circuit) converts the high impedance signal of the piezoelectric material into a voltage signal with a low impedance of typically 100 Ω. A low impedance signal is advantageous because it can be transmitted across long cable lengths without a loss of signal quality.

  6. Charge amplifier - Wikipedia

    en.wikipedia.org/wiki/Charge_amplifier

    Piezoelectric transducers with charge output and external charge amplifiers can be used at higher temperatures than those with internal electronics [2] Gain is dependent only on the feedback capacitor, unlike voltage amplifiers, which are affected greatly by the input capacitance of the amplifier and the parallel capacitance of the cable [ 2 ...

  7. Piezotronics - Wikipedia

    en.wikipedia.org/wiki/Piezotronics

    Working mechanism for piezoelectric devices with one end of the piezoelectric material is fixed. The induced piezopotential distribution is similar to the applied gate voltage in a traditional field-effect transistor, as shown in (b). Schematic diagram showing the three-way coupling among piezoelectricity, photoexcitation and semiconductor.

  8. Buzzer - Wikipedia

    en.wikipedia.org/wiki/Buzzer

    A buzzer or beeper is an audio signaling device, [1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, train and confirmation of user input such as a mouse click or keystroke.

  9. Piezoelectric microelectromechanical systems - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_micro...

    A piezoelectric microelectromechanical system (piezoMEMS) is a miniature or microscopic device that uses piezoelectricity to generate motion and carry out its tasks. It is a microelectromechanical system that takes advantage of an electrical potential that appears under mechanical stress .
