[0002] Piezoelectric ceramics are ceramic materials that can convert mechanical energy into electrical energy. In addition to piezoelectricity, piezoelectric ceramics also possess dielectric and elastic properties, and have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, and other applications. Piezoelectric ceramics require polarization during production. This process involves subjecting piezoelectric ceramics to special electric field stimulation to alter their lattice structure and charge distribution, thereby improving their piezoelectric properties. This electric field stimulation is called polarization, and piezoelectric ceramics require tooling during the polarization process.
