Talk about the development history of piezoelectric ceramic plate

The history of the development of piezoelectric ceramic plates can be traced back to 1880. ‍‍ In 1880, the Curie brothers discovered the electric piezoelectric effect of ‍‍, from which ‍‍ began the further study of ‍‍ of ‍ piezoelectrics.

‍‍ In 1894, ‍‍, a new research scholar further expanded the piezoelectric effect and pointed out that the quartz stone was a representative of piezoelectric crystal. ‍‍ Later, until the Second World War, people discovered the ceramic piezoelectric material, ‍ piezoelectric made ‍‍ very important progress.

‍‍ In the 1940s, the insulation laboratory ‍‍ of ‍‍, Massachusetts Institute of Technology, found that ‍‍ applied a high voltage electric field on barium titanate ferroelectric ceramics, ‍‍ would make it have piezoelectric effect, and therefore piezoelectric ceramics were produced.

After 1995, the United States discovered more superior piezoelectric ceramics, piezoelectric related components for ‍‍ more detailed expansion.

More and more in the late 1970 s, piezoelectric products, ‍ ‍ piezoelectric ceramic chip is a very typical piezoelectric element, the piezoelectric ceramic piece actually is a big advantage, because ‍ ‍ dielectric properties, and elastic properties are relatively good, ‍ ‍ it piezoelectric makes this product can be applied to some special fields, ‍‍ and its physical mechanism is special. ‍‍ has the characteristics of sensitivity, which can convert extremely weak mechanical vibration into electrical signals. Therefore, ‍‍ is widely used in all walks of life.

The shape variable generated by piezoelectric ceramics under the action of electric field is the main application principle of the current ‍‍ piezoelectric ‍‍ products. At present, ‍‍ piezoelectric ceramic plate is also a common piezoelectric component with good comprehensive performance. In recent years, more and more enterprises produce piezoelectric ceramic pieces in our country, ‍‍, but the procurement personnel also need to pay attention to some of the technology of ‍‍ piezoelectric ceramic pieces, including some dimensions and so on, so that we can buy the appropriate piezoelectric ceramic pieces. ‍
