Piezoelectric transducers are ultrasonic sensors made by using the piezoelectric effect produced by certain dielectrics. The so-called piezoelectric effect refers to the phenomenon that when certain dielectrics undergo deformation (including bending and stretching deformation) due to the polarizatio

Question 1: Under the excitation of the piezoelectric ceramic driving power, the maximum drive displacement drops from 45um to 33um. What is the reason?We need to explain in different situations. If there is no ignition, it means there is no breakdown or short circuit, and there is displacement outp

Piezoelectric films are widely used because of their excellent performance. Piezoelectric thick films can be used to manufacture a variety of micro devices, such as micropumps, ultrasonic motors, resonators, pyroelectric thick film sensors, thick film actuators, micro-energy pickups, etc. 1. Hydroph

Piezoelectric materials are functional materials that realize the conversion between mechanical energy and electrical energy. Its development has a long history. Since the discovery of the piezoelectric effect on quartz crystals by the CURIE brothers in the 1880s, piezoelectric materials have begun

With the production technology and the continuous expansion of applications, PZT piezoelectric ceramics have been widely entered into people's vision, and their popularity is also rising.PZT piezoelectric ceramics have the inverse piezoelectric effect, that is, the micro displacement of the correspo

In the special piezo ceramic industry, there are also some "flavoring agents". Although the amount added in the piezo ceramic formula is very small, it has a very important role in improving the processing performance of special piezo ceramics and improving the performance of special ceramic product

NDT is the abbreviation of Non-destructive Testing.NDT refers to a test method that does not damage or affect the future performance or use of materials or workpieces.By using NDT, defects in the interior and surface of materials or workpieces can be found, geometric characteristics and dimensions o

Touch screen (also known as "touch screen", "touch panel") is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the The haptic feedback system can drive various connected devices according to a pre-programmed p

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

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

Piezoelectric ceramic hydrophones have a wide range of applications in sonar due to their flatness, stable performance and simple structure. The main failure mode of piezoelectric ceramic hydrophones is the reduction in the insulation resistance. The average insulation resistance of the hydrophone i

At present, piezoelectric ceramic transformer has been widely used in a series of fields, including household appliances and high-tech military products. One of the most typical applications is to drive cold cathode fluorescent lamp. This is because the voltage and current characteristics of piezo

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

The rapid development of the world economy has led to a sharp increase in energy consumption. With the depletion of non-renewable energy sources and the protection of the environment, countries are vigorously developing sustainable clean energy. Clean energy such as light, wind and solar energy is g
