Some ceramics such as barium titanate, lead zirconate titanate and potassium sodium niobate are also in a structure to show piezoelectric properties. The cutting surfaces of the crystal with respect to the center must be symmetrical because the cutting shapes of the crystals directly affect the vibration frequency they generate and the voltage they generate. It is not possible to use the crystals that make up the piezo phenomenon as they are in nature. These features make it possible for a number of special uses such as ultrasonic sound generators and ultrasonic devices for intrusion alarms, automatic door openers and remote control devices. With the help of reverse piezoelectric, a significant shape change can be created in a ceramic material.

Piezo effect from mechanical energy to voltage generation using piezoelectric property The generation of mechanical vibration from voltage is also called the inverse piezo event. This behavior is called piezoelectric property. Thus, the electrical effect turns into mechanical magnitude. If the direction of the field changes, the same signed charges repel each other and the crystalline becomes shorter. On the other hand, if a voltage is applied between the two ends of the same crystal, (-) charges are drawn towards the (+) electrode, (+) charges towards the (-) electrode, the distance between (-) and (+) charge centers increases, and as a result, the length of the crystal increases.

Thus, mechanical energy turns into electrical magnitude. If pressure is applied to an asymmetric ionic crystal with continuous cleavage, the distance between the poles decreases, the charge accumulation on its surface increases, so a voltage difference arises between the two ends, and if they are coupled with a conductor, current occurs. If the material is not short-circuited, the stress applied creates a voltage in the material. This effect is directly related to the change in polarization density inside the material. Piezoelectric property is the ability of a material to change electric field or electric potential as a result of mechanical pressure applied to certain materials.
