• What’s the piezoelectric material and structure ?

  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

• High frequency current and working process of piezoelectric ceramics

  The principle of the piezoelectric effect of piezoelectric ceramics is that when a pressure is applied to a piezoelectric material, it will generate a potential difference (called the positive piezoelectric effect). Otherwise, a voltage will generate mechanical stress (called the inverse piezoelectr
