The higher-grade lighters are not equipped with flint inside, and their ignition devices are similar, most of which are ignited by piezoelectric ceramics through tip discharge. Some solid dielectrics have a special phenomenon due to the special structure of the lattice. That is, when the piezo cryst

Piezoelectric material is a special dielectric material with piezoelectric effect and inverse piezoelectric effect. The piezoelectric effect is the characteristic of some piezo crystals discovered by the French P. Curie and J. Curie brothers in 1880. When a piezoelectric force exerts a mechanical fo

Piezoelectric ceramic hydrophones have a wide range of applications in sonar due to their flatness, stable performance and simple structure. The main failure mode of piezoelectric ceramic hydrophones is the reduction in the insulation resistance. The average insulation resistance of the hydrophone i

The application of the positive piezoelectric effect is mainly used for gas igniters, such as gas stoves. Ignition system for gas lighters, etc. The basic working principle is: compressing a spring by an external force, releasing it after pressing to the apex, and the spring force pushes a heavy ham

Application of piezoelectric ceramics transducerPiezoelectric ceramics have been widely used due to their piezoelectricity and the resulting diversity of electromechanical properties. These applications can generally be divided into two broad categories, namely as piezoelectric vibrators. When is us
