Applications
Piezoelectric disc actuators are small, thin, lightweight, quiet, extremely fflcient with low power consumption, and have fast response times. They are widely used in a broad range of applications, especially air and fuid pumps, valves, and in commercial household applications as well. Piezoelectric discs do not require lubrication for operation and can function in harsh vacuum and cryogenic environments.
The most common application for piezo ceramic discs is in air and fluid pumps. In the example of a fluid pump, as the actuator bends, the rapid deformation causes a difference in pressure between the outside of the chamber and the inside of the chamber, forcing the fluid to move through the chamber. When the current is created in the fluid and subsequently released, the piezo disc goes back to its original state. This can be seen in pumps for fish tanks, automatic espresso machines, propane stoves, and much more. When the piezo element in the pump receives the electrical voltage, the unimorph or bimorph actuator deforms to generate movement through the pump. Liquid cooling systems for CPUs computer, LED lights, etc. also uilie piezoelecric discs. To cool CPUs, disc actuators move coolant through the system and to the radiator which helps it cool.
Sound converter
Sound converters are one of the most common applications. Piezoelectric ceramics can be used as sound converters for devices such as pickups, microphones, headphones, buzzers, ultrasonic depth detectors, sonar, and material ultrasonic flaw detectors. The buzzer on children's toys vibrates through the reverse piezoelectric effect of piezoelectric ceramics, producing sounds that can be heard by the human ear. Piezoelectric ceramics can generate vibrations of different frequencies through the control of electronic circuits, thereby emitting various different sounds. For example, electronic music greeting cards convert AC audio electrical signals into sound signals through the inverse piezoelectric effect.
Piezoelectric detonator
Since the British invented tanks during World War I and used them for the first time in battles on the Somme River in France, which dealt a heavy blow to the German army, tanks have shown their skills in multiple battles. However, in the 1960s and 1970s, due to the invention of anti tank weapons, tanks lost their former glory. The armor piercing shells fired by anti tank guns will immediately explode upon contact with the tank, shattering it to pieces. This is because the warhead is equipped with piezoelectric ceramics, which can convert the strong mechanical force during collision into an instantaneous high voltage, explode sparks, and ignite explosives.
Ultrasonic transducer
Suitable for use in ultrasonic welding equipment and ultrasonic cleaning equipment, mainly made of high-power emitting piezoelectric ceramics. Ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. As an energy converter, its function is to convert input electrical power into mechanical power (i.e. ultrasonic) and then transmit it out, while it consumes very little power.
Sonar
In naval warfare, the most difficult thing to deal with is submarines. They can dive underwater for a long time and sneak attacks on ports and ships unnoticed, causing great headaches for the enemy. How to search for enemy submarines? It's not enough to rely on the eyes, nor is it enough to use radar, because electromagnetic waves will rapidly attenuate in seawater and cannot effectively transmit signals. Detecting submarines relies on sonar - underwater ears. Piezoelectric ceramics are materials used to manufacture sonar. They emit ultrasonic waves, which are reflected back when encountering submarines. After being received and processed, they can measure the orientation and distance of enemy submarines.
