Piezoelectric sensor

A piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated)

Frequency response of a piezoelectric sensor; output voltage vs applied force

In the flat region, the sensor can be modeled as a voltage source in series with the sensor's capacitance or a charge source in parallel with the capacitance

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'.
