Problems solved by technology

It can be seen that there will be more organic solvents in the electrode slurry used in the traditional process. In the process of drying and burning the electrode, it is inevitable to discharge a large amount of waste gas, causing air pollution.
[0004] In summary, the existing processing technology of piezoelectric ceramics obviously has inconvenience and defects in actual use, so it is necessary to improve

Abstract

The invention relates to the technical field of piezoelectric ceramics, in particular to a piezoelectric ceramic and a device thereof, the piezoelectric ceramic comprises at least one piezoelectric ceramic piece, a seat tool clamp and at least two electric conductors used for clamping the piezoelectric ceramic piece, and the two electric conductors are respectively provided with electric connection points of an external power supply; the electric connection point is connected with a power supply; therefore, the invention provides the piezoelectric ceramic which is convenient to process, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of piezoelectric ceramics, in particular to a piezoelectric ceramic and a device thereof. Background technique [0002] Piezoelectric ceramic is a special ceramic material widely used in ultrasonic, electroacoustic, communication, ranging, underwater acoustic detection, sensing and other fields. The piezoelectric effect is that when the piezoelectric material is subjected to pressure, the piezoelectric material will deform , thereby generating electricity on both electrodes of the material. Conversely, when a voltage is applied to the two electrodes, the piezoelectric ceramic will deform, which is called the inverse piezoelectric effect. like Figure 1A Shown: when the forward DC voltage is applied, the thickness of the piezoelectric ceramic becomes larger; such as Figure 1B Shown: when the DC voltage is reversed, the thickness of the piezoelectric ceramic becomes smaller; such as Figure 1C Shown: When ...
