Piezoelectric Ceramics Use Very Widely

Sinocera Piezotronics, INC | Updated: Oct 26, 2017

Piezoelectric Ceramics Use very widely

Piezoelectric ceramics, piezoelectric ceramic chips are widely used. Let's take a few examples:

Piezoelectric Ceramics Use 1, Sound Converter Sound converter is one of the most common applications. Such as pickups, microphones, headphones, buzzers, ultrasonic depth sounder, sonar, material ultrasonic flaw detector, etc. can be done with piezoelectric ceramic sound converter. Such as children's toys on the buzzer is the current through the piezoelectric ceramic reverse piezoelectric effect of vibration, and issued by the human ear can hear the sound. Piezoelectric ceramics through the electronic circuit control, can produce different frequencies of vibration, which issued a variety of different sounds. Such as electronic music greeting cards, is through the reverse piezoelectric effect of the AC audio signal into a sound signal.

Piezoelectric ceramic use 2, the piezoelectric detonator Since the first World War in the British army invented the tank, and for the first time in the battle of the French Somme used to hit the Germans, the tanks in the battle to show their talents. However, in the 1960s and 1970s, due to the invention of anti-tank weapons, tanks lost their former glory. Anti-tank guns emitted by the armor-piercing missile contact tanks, it will immediately explode, the tank fried crushed. This is because the warhead is equipped with piezoelectric ceramics, it can touch when the powerful mechanical force into an instant high voltage, the outbreak of spark and detonated explosives.

Piezoelectric ceramic use 3, piezoelectric lighters Now gas stove on the use of a new type of electronic lighters, is made of piezoelectric ceramics. As long as the pressure with your fingers pressure button, the lighter on the piezoelectric ceramic can produce high voltage, the formation of spark and ignite the gas can be long-term use. Therefore, the piezoelectric lighter is not only easy to use, safe and reliable, and long life, such as a lead-acid lead lead ceramic made of lighters can be used more than 100 million times.

Piezoelectric ceramic use 4, anti-nuclear goggles Nuclear test personnel with transparent piezoelectric ceramics made of goggles, when the nuclear explosion of light radiation to the extent of danger, the goggles in the piezoelectric ceramic put it change Into the instantaneous high-voltage, in 1/1000 s, the light intensity can be reduced to only 1/10000, when the dangerous light disappeared, but also to restore to the original state. This goggles are simple, only a few dozen grams, and are easy to carry on a helmet.

Piezoelectric ceramic use 5, ultrasonic transducer for ultrasonic welding equipment and ultrasonic cleaning equipment, mainly using high-power emission-type piezoelectric ceramic production, ultrasonic transducer is a high-frequency energy can be converted into mechanical energy device , The ultrasonic transducer as an energy conversion device, its function is to convert the input power into mechanical power (ie, ultrasonic) and then passed out, and its own consumption of a small part of the power.
