Introduction

Piezoelectric ceramics possess the characteristic of converting external forces into electrical energy; that is, they can convert extremely weak mechanical vibrations into electrical signals, and simultaneously convert electrical signals into electrical signals.

By replacing mechanical vibration with this property of piezoelectric ceramics, it has been widely applied in sonar systems, weather detection, and household appliances.

GB/T 2414 "Test Methods for Performance of Piezoelectric Ceramic Materials" is proposed to consist of two parts.

— Part 1: Radial Stretching Vibration Modes of Circular Piezoelectric Ceramics. The aim is to define the performance parameters of piezoelectric ceramics under radial stretching vibration modes. Numerical representation.

— Part 2: Transverse Length Expansion Vibration Modes. The aim is to define the properties of piezoelectric ceramics in transverse expansion vibration modes.

Energy parameter characterization.
