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

Method for preparing piezoelectric filmThe preparation methods of piezoelectric thin films are mainly traditional vacuum coating methods, including vacuum evaporation coating, sputtering coating, chemical vapor deposition coating is prepared in a thickness of 0 ~ 18μm, new sol-gel method, hydrotherm

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

1)I want to apply a layer of paint on my piezoelectric ceramic,this will reduce its displacement.Answer: Any additional material parallel to the piezoelectric ceramic will increase the load of the piezoelectric ceramic, thereby reducing its performance. However, in most cases, the stiffness of the o
