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

The piezoelectric sensor is made of piezoelectric effect generated by some dielectric after loading. The piezoelectric effect refers to certain dielectric in one direction by external force and deformation (including bending and deformation), due to the polarization of the internal charge, will be p

Piezoelectric material is a kind of crystal material which appears voltage between two ends when subjected to pressure.Piezoelectric ceramics refers to piezoelectric polycrystals. Piezoelectric ceramic is a polycrystal formed by mixing, molding, sintering at high temperature, irregularly assembling

A transducer is any device used to convert electrical energy, mechanical energy or acoustic energy from one form to another; typically when converting input energy into output energy.For transduction to occur, a change from one form of energy must also take place, such as a conversion from mechanica

Leak detection and gas flow measurementGas flow measurement is one of the important methods in chemical industry. There are a variety of flow detection, such as float flowmeter. The main advantage of using ultrasonic transducer is not to impede the flow of fluid.Distance Measurement:Ultrasonic dista

Industrial production labor involved in the process of ultrasonic cleaning machine belong to the scope of industrial cleaning. Food industry, textile industry, paper industry, printing industry, petroleum processing industry, transportation industry, power industry, metal processing industry, machin

Ultrasonic welding takes advantages of the friction energy generated by the ultrasound at the boundary surfaces. When two performs are pressed together at their connecting surface and excited using high-frequency ultrasound, the surface of the two parts generate so much energy that their connecting

Transducer are devices how converting energy from one to another. As already mentioned, transducer, piezoelectric operate in two directions. Process pressure and vibration into electrical signals, but also, conversely, the electrical signals in pressure, sound and vibration. Piezoelectric transducer

Piezlelectric ceramics are a kind of functional material which can convert  mechanical energy and electric energy into each other. Piezoelectric effect is a property  that some of crystal and piezoelectric ceramics have. When load on the load in some dielectric, so that it will produce polarization,
