Piezoelectric ceramic is different from quartz crystal, the former is polycrystalline piezoelectric material, and the latter is single crystal. The piezoelectric ceramics don’t have piezoelectric effect before polarization. After poling treatment, the piezoelectric effect is very obvious, and it has high piezoelectric coefficient. The piezoelectric coefficient is several times larger than that of quartz crystal.
 
Piezo is used to describe materials that accumulate a charge as a result of the piezoelectric effect. Piezo materials, including crystals and ceramics generate a voltage in response to an applied mechanical stress. In what is known as the inverse piezoelectric effect, these same materials will lengthen or shorten in response to an applied voltage.
The voltages, movements, and forces generated by piezo materials are small and usually require amplification. For example, a typical disc of piezolectric ceramic will increase or decrease in size by only a small fraction of a millimeter. In spite of this minor change of thickness, piezoelectric materials are used in many far-reaching applications.
Piezoelectric ceramics are a preferred material choice due to their ability to be tailored to meet the requirements of a specific purpose. Currently, PZT (lead zirconate titanate) materials are the most widely used piezo ceramics. They offer greater sensitivity and higher operating temperatures than other piezo ceramics
 
Mechanical compression or tension on a poled piezoelectric ceramic element changes the dipole moment, creating a voltage. Compression along the direction of polarization, or tension perpendicular to the direction of polarization, generates voltage of the same polarity as the poling voltage . Tension along the direction of polarization, or compression perpendicular to the direction of polarization, generates a voltage with polarity opposite that of the poling voltage . These actions are generator actions -- the ceramic element converts the mechanical energy of compression or tension into electrical energy. This behavior is used in fuel-igniting devices, solid state batteries, force-sensing devices, and other products. Values for compressive stress and the voltage (or field strength) generated by applying stress to a piezoelectric ceramic element are linearly proportional up to a material-specific stress. The same is true for applied voltage and generated strain.
 
If a voltage of the same polarity as the poling voltage is applied to a ceramic element, in the direction of the poling voltage, the element will lengthen and its diameter will become smaller . If a voltage of polarity opposite that of the poling voltage is applied, the element will become shorter and broader. If an alternating voltage is applied, the element will lengthen and shorten cyclically, at the frequency of the applied voltage. This is motor action -- electrical energy is converted into mechanical energy. The principle is adapted to piezoelectric motors, sound or ultrasound generating devices, and many other
