    What is the function of the piezoelectric ceramic crystal of drive circuit inductor

    The function of the piezoelectric ceramic layer inductor is mainly to transmit DC and block AC. It mainly plays the role of filtering, oscillation, delay and notch in the circuit. Inductive coils block AC current. The size of the blocking effect is called inductive reactance x1, and the unit is ohms

    Storage instructions and vibration modes of piezoelectric ceramics

    Piezoelectric ceramic plates have no piezoelectric effect or anti-piezoelectric effect, because their interiors cancel each other out before polarization. Therefore, the answer to question one is no. As for the temperature resistance of the piezoelectric ceramic sheet, it is usually about half of th

    Explanation of piezoelectric ceramic vibration frequency and application on transducer

    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

    How to estimate the displacement of ultrasonic piezoelectric ceramics transducer

    The displacement of the ultrasonic piezo ceramic transducer is estimated by using the inverse piezoelectric effect, that is, when a voltage is applied to the piezoelectric ceramics, the piezoelectric ceramics will be deformed and displaced under the influence of the electric field. Rough estimate of

    What is the pressure resistance of ultrasonic piezoelectric ceramics?

    Single-layer piezoelectric ceramics, also commonly referred to as ultrasonic piezoelectric ceramic sheets, contain only one piezo ceramic crystals inside, and there is no electrode layer inside, and the outer surface has only electrode layers. Unlike multilayer piezoelectric ceramics, there are many

    Principle and Material Classification of Ultrasonic Piezoelectric Ceramic Transducer

    The principle of the piezoelectric effect of an ultrasonic piezoelectric ceramic sheet is that if pressure is applied to a piezoelectric material, it will generate a potential difference (called the positive piezoelectric effect), and if a voltage is applied, it will generate mechanical stress (call
