Pzt-4/Pzt-8 Piezo Ultrasonic Transducer Sensors 50*17*6.5 Piezoelectric Ceramic Components

Some anisotropic crystals undergo deformation under mechanical force, causing relative displacement of charged particles, resulting in positive and negative bound charges on the surface of the crystal. This phenomenon is called the piezoelectric effect. This property of crystals is called piezoelectricity. Piezoelectricity was discovered by the brothers J. Curie and P. Curie in 1880. A few months later, they used experiments to verify the inverse piezoelectric effect, which means that when a voltage is applied to a crystal, the crystal undergoes geometric deformation.
