Schematic symbol and electronic model for a piezoelectric sensor. Date: ... This W3C-unspecified circuit diagram was created with the Electrical Symbols Library.
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.
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]
Rough sketch of piezoelectric sensor frequency response (relationship between force input and voltage output vs frequency). Low frequencies are filtered out by the leakage resistance, and high frequencies resonate. The useful region for a sensor is usually in the flat area. Imitating graphs on and .

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.
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 ...
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.
Figure 1. Diagram of Piezo Inchworm Motor in action. Figure 2. Six Step Actuation Processes of the Piezo Inchworm Motor. In its simplest form, the inchworm motor uses three piezo-actuators (2 and 3, see Figure 1.) mounted inside a tube (1) and electrified in sequence to grip a shaft (4) which is then moved in a linear direction.
