Techopedia Explains Piezoelectricity

Piezoelectricity is primarily used as input for certain components such as actuators, sensors and oscillators. It is used to detect voltages, sound waves, electronic frequency, pressure and mechanical movements. The aforementioned components use the electric charge generated from a piezoelectric material for certain processes or functions. For example, a crystal oscillator uses piezoelectricity to deliver stable clock signals to the integrated circuits in computers and cellphones. Piezoelectricity is also commonly used in certain devices such as piezometers, piezoelectric accelerometers and other similar devices.
