Piezoelectric sensorThe application of piezoelectric sensors for sensing and excitation extends to many areas. This article mainly introduces the induction of some physical intensities, namely acceleration, vibration, oscillation and pressure, which can be considered similar from the perspective of

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

Piezoelectric ceramics are mainly used to guide special piezoceramics with low thermal coefficient and poor heat transfer. The thermal insulation piezo ceramics mainly use zirconia and alumina ceramic materials. The zirconia materials have low thermal conductivity and are used as thermal insulation

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

The theoretical research and application status of piezo ceramic disc transducer are discussed and commented comprehensively, and the existing problems are analyzed. Piezoelectric ceramic transformer is a new type of solid-state electronic device. It has the advantages of simple structure and proces

Ultrasonic diffraction and scattering characteristics:When the ultrasonic wave propagates through the medium, it encounters a heterogeneous interface (such as a defect). According to the huygens principle, a diffraction phenomenon occurs at the edge thereof, and a newly excited diffraction wave is g

1. What is the resonant frequency of a piezoelectric ceramic crystal?For the resonant frequency of the 1Mhz piezoelectric ceramic crystal, the relevant factors are connected with the thickness of the ceramic sheet and the size and diameter of the piezo ceramic sheet. If the piezoelectric ceramic pie
