For piezoelectric ceramic transducers, an alternating current frequency will be generated after the application of alternating current. If the frequency is exactly equal to the natural frequency of the piezoelectric ceramic, the piezoelectric ceramic will generate resonance frequency. In addition, t

When some dielectrics are deformed by an external force in a certain direction, polarization occurs inside them, and positive and negative opposite charges appear on the two opposite surfaces thereof. When the external force is removed, it will return to the uncharged state. This phenomenon is calle

With the propagation of ultrasonic vibration in the medium, its essence is the mechanical vibration is propagating in the elastic medium in the form of wave, it is generally considered that its frequency should be above 20 kHz. Ultrasonic non-destructive testing commonly used at 0 4 to 5 MHz. Ultras

Application of piezoelectric ceramics transducerPiezoelectric ceramics have been widely used due to their piezoelectricity and the resulting diversity of electromechanical properties. These applications can generally be divided into two broad categories, namely as piezoelectric vibrators. When is us

Ultrasonic motor is a new type of motor driven by piezoelectric ceramic excitation ultrasonic wave. It has the advantages of low speed and large torque, low inertia, fast response and no interference from magnetic field. Due to the above advantages of ultrasonic motor, ultrasonic motor technology ha
