Ultrasonic flaw detection is a method that can penetrate into the depths of the metal material by ultrasonic, and when it from a cross-section into another section, the edge of the interface characteristics of reflection will check the parts of a defect, when the ultrasonic beam from the part surfac

A piezoelectric sensor converts a physical parameter, such as acceleration or pressure, into an electrical signal. In some sensors the physical parameter acts directly on the piezoelectric element; in other devices an acoustical signal establishes vibrations in the element and the vibrations are, in

In recent years, with the semiconductor integrated circuit to the high density, micro-development and the high precision of various processing requirements, as the key device actuator also put forward higher requirements. In recent years, piezoelectric and electrostrictive ceramic actuators develope

The piezoelectric actuator by piezoelectric ceramics with applied voltage deformation (elongation and contraction) characteristics, widely used in mobile phone camera module in automatic focusing, digital camera image stabilization system and position control device.

There are two types of piezoelectric generators, including single layer piezoelectric generator and multilayer piezoelectric generatorSingle-Layer Piezoelectric Generators

Piezoelectric ceramic is a two-way effect element, that is, it is added to the electricity, it will produce mechanical deformation, if forced to produce mechanical deformation, it generates electricity. And the bidirectional conversion efficiency is very high, of course, the conversion efficiency is

An accelerometer is a type of sensor that measures force due to acceleration of the sensor. The piezoelectric acceleration sensor is also called the piezoelectric accelerometer. It also belongs to the inertial sensor. It is the use of certain substances such as the piezoelectric effect of quartz cry

Piezoelectric ceramics play a more and more important role in our life, we should realize the development process of piezoelectric ceramics. In 1880, the Curie brothers first discovered the piezoelectric effect of tourmaline, began the history of piezoelectricity. The following year, Curie brothers
