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. Integrated Electronics Piezo-Electric - Wikipedia

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

   The sensor circuit is supplied with constant current. A distinguishing feature of the IEPE principle is that the power supply and the sensor signal are transmitted via one shielded wire. Most IEPE sensors work at a constant current between 2 and 20 mA. A common value is 4 mA. The higher the constant current the longer the possible cable length.

   Schematic symbol and electronic model for a piezoelectric sensor. Date: ... This W3C-unspecified circuit diagram was created with the Electrical Symbols Library.

5. 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.

6. Piezoelectric accelerometer - Wikipedia

   en.wikipedia.org/wiki/Piezoelectric_accelerometer

   The high modulus of elasticity of piezoelectric materials makes the piezoelectric sensor a more viable solution to the problems identified with the strain gage accelerometer. Simply stated, the inherent properties of the piezoelectric accelerometers made it a much better alternative to the strain gage types because of its high frequency ...

7. Charge amplifier - Wikipedia

   en.wikipedia.org/wiki/Charge_amplifier

   Schematic of a charge amplifier with a piezoelectric sensor. The amplifier offsets the input current using a feedback reference capacitor, and produces an output voltage inversely proportional to the value of the reference capacitor but proportional to the total input charge flowing during the specified time period.

8. 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 .
