Piezoelectric materials have an excellent ability to convert mechanical force into electrical charge and vice versa. Piezoelectric ceramics such as lead zirconate titanate, lead magnesium niobate-lead titanate, etc. have been widely used in sensors, actuators, transducers and energy harvesters. Howe
Piezoelectric shock absorption system The piezoelectric damping system can be divided into passive damping and active damping. Passive vibration reduction is to prepare a layer of resistive film on the surface of piezoelectric ceramics. The piezoelectric ceramic converts vibration or noise into elec
The cost of single-layer piezoelectric ceramics is very competitive, and its series resonance point is relatively high, which can exceed the megahertz level, and the vibration strength and output working capacity of the single-layer piezoelectric ceramics at the series resonance point are Quite larg
The piezoelectric ceramic sheet is a key component of the laser positioning system in the working process. When in use, it mainly uses the piezoelectric conversion characteristics of the piezoelectric ceramic. When in use, the length of the laser cavity is adjusted by adjusting the voltage to ensure
Piezoelectric ceramics are often used in the field of biomedicine for their wear resistance, long life and biocompatibility, but it is more than that. It is concluded that piezoelectric ceramics have great prospects in the medical device industry. In recent years, the medical device industry has con
What is a piezoelectric ceramics? Piezo ceramics ultrasonic sensor is a device that uses the piezoelectric effect to measure the electromotive force caused by the mechanical force applied to the piezoelectric material. They are based on the principle of electromechanical energy conversion, mainly me
Piezoelectric ceramics sensors are ultrasonic sensors made by using the piezoelectric effect produced by certain dielectrics. The so-called piezoelectric effect refers to the phenomenon that certain dielectrics undergo deformation (including bending and stretching deformation) due to the polarizatio
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
