Problems solved by technology

However, the structure of the test fixture of the traditional polarization device is too unreasonable, and the operation is inconvenient, especially it is not easy to be used repeatedly for plugging and unplugging. It is difficult to clamp piezoelectric ceramic sheets of different thicknesses, so the same test fixture cannot realize piezoelectric ceramics of different thicknesses. Polarization of the sheet
