Application of Piezoelectric Ceramics in Electromechanical Conversion

Piezoelectric ceramics are known for so-called piezoelectric and inverse piezoelectric effects, which cause the crystal to generate an electric potential when subjected to mechanical vibration. Conversely, the inverse piezoelectric effect causes the crystal to vibrate when placed in an electric field. Among piezoelectric materials, quartz has long been called a single crystal piezoelectric substance. However, the range of applications of these materials is relatively limited, mainly due to the poor crystal stability and limited freedom of quartz properties.

Later, barium titanate (BaTiO3), a piezoelectric ceramic sheet, was introduced into ultrasonic transducer applications, mainly for fish finder; recently, there was a titanate, lead zirconate system (PbTiO3PbZrO3), which has electromechanical Conversion efficiency and stability (including temperature characteristics) are far superior to existing materials. It greatly expands the range of applications of piezoelectric ceramics. When comparing other piezoelectric materials, it has the following advantages:

High electromechanical conversion efficiency; good machinability; different material compositions can achieve a wide range of characteristics (high degree of freedom design); high stability; suitable for mass production, economical. As a pioneer in the piezoelectric ceramic industry, it offers a wide range of piezoelectric applications.
