What are Piezoelectric Effect Applications?

The piezoelectric effect is the conversion of mechanical energy into electrical energy by means of crystals. A regular crystal has a repeating structure of atoms that are held together by a bond. This unit cell is known as the unit of the piezoelectric effect. In contrast, a symmetrical crystal such as iron would be useless for piezoelectric purposes. Hence, some applications for the physics of this effect include atomic resolution, ultra-fine focusing of optical assemblies, and ignition sources. These include electric cigarette lighters and gas grills. In electric cigarette lighters, a piezoelectric crystal carries a voltage across a spark gap and generates an electrical current. Large ovens, gas burners, and microwaves also use a piezoelectric power system.

The hammer striking a piezo material generates a spark that ignites the flammable gas. Piezoelectric sensors can detect minute disturbances in objects, making them ideal for industrial nondestructive testing or medical imaging.

The piezoelectric effect can be used in many areas of science. Some of the more obvious uses of piezoelectric materials are in the fabrication and sensing of sound. It is used in spark lighters, ultrasound transducers, acoustic guitar pickups, and vibration sensors. It has also been applied in rockets. In fact, NASA has been investigating the use of piezoelectric materials for a long time. The technology can be harnessed for radio waves and other devices that transmit information.

The piezoelectric effects high-frequency pulses can be generated to measure temperature. Its low frequency can also be used to generate ultrasound waves. Likewise, the piezoelectric effect can be used to create sensors and actuators. For example, a hammer striking a piezoelectric material can be used to detect minute disturbances.

Another common application of the piezoelectric effect is in the field of electronics. Its main function is to convert mechanical energy into electrical energy. The result is a signal that can be stored in an electronic device. Piezoelectric materials are highly sensitive, making them ideal for detecting minute disturbances. However, these devices can be difficult to manufacture if they are not designed properly.
