Piezoelectric materials are functional materials that realize the conversion between mechanical energy and electrical energy. Its development has a long history. Since the discovery of the piezoelectric effect on quartz crystals by the CURIE brothers in the 1880s, piezoelectric materials have attrac

PZT can not only be used to make various piezoelectric products, but in recent years PZT is gradually applied to structural damage detection. According to the positive and inverse piezoelectric effects of piezoelectric materials, PZT piezoelectric ceramics can be used as both driving and sensing ele

The transducer array are the key components in the sonar system. It is a device that realizes the mutual conversion of electro-acoustic energy. The performance of the transducer and the transducer array mainly depends on the performance, structure and manufacturing process of the transducing materia

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

Piezoelectric ceramics are a kind of polycrystals with piezoelectric properties and an important part of information functional piezoelectric ceramics. With the advantages of high electromechanical coupling coefficient, low price and easy mass production, piezoelectric ceramics have been widely used

Piezoelectric ceramics are a type of crystal material that undergoes a shape change such as compression or elongation when subjected to mechanical stress. As the shape changes, different charges are generated on both sides of the crystal. Conversely, adding a different voltage across the linear piez
