50*17*6.5mm Piezo Ceramic Ring Pzt8 Ultrasonic Transducer Sensor For Ultrasonic Welder
how do piezoelectric ceramic materials work?
The piezoelectric ceramic plate is the main component of the buzzer plate (device), so it is called a piezoelectric element. The reason why piezoelectric ceramic plates can emit the sound of beeping is to use the principle of piezoelectric effect. The piezoelectric effect has a positive piezoelectric effect and inverse piezoelectric effect two kinds.
Piezoelectric effect: when the piezoelectric ceramic chip is applied to an external force, the piezoelectric chip will produce an electric charge, this phenomenon is called the positive piezoelectric effect; On the contrary, when the electric field is applied to the piezoelectric plate, the piezoelectric ceramic plate will produce mechanical deformation, and its strain is proportional to the strength of the electric field, which is called the inverse piezoelectric effect, the stronger the electric field intensity, the greater the amplitude of vibration. This phenomenon is called the inverse piezoelectric effect: voltage-pressure and all kinds of piezoelectric ceramic devices work by using this characteristic.
