With the continuous development of computer technology, computers have become an indispensable control for ultrasonic high focus piezoelectric treatment systems. In the actual treatment process, the target should be tracked and monitored in the real time through the computer! The target is compared

With the development of science and technology, the non-destructive testing technology of temperature field has made great progress, and some non-destructive side temperature methods of HIFU piezo ceramic have been proposed.Such as electrical impedance tomography, magnetic resonance (M IR) ultrasoun

In order to realize the HIFU ultrasound piezo, the traditional methods mostly use a single frequency ultrasonic transducer, and the use of the same focusing system to achieve the focus of the two frequency ultrasound is rarely reported. In 1996, Japanese scholar S. Umemura et al. studied a technique

(1) About planar annular array transducer. A concentric small circular area is dug in the center of the circular piston source to form an annular planar sound source.The sound pressure generated by the annular planar sound source at any point in space can be regarded as the sound pressure generated

pressure sensitive piezoelectric sensorAs a new type micro-motor, its own technological development of piezoelectric ring transducer can not be separated from the electronic control and drive. The advantages and disadvantages of the control technology are directly

piezoelectric transducer used for ultrasonic motorsWith the development of society, Ultrasonic motors have become more and more indispensable.electromechanical energy equipment of hifu ultrasound piezo is used for human beings. Piezo ceramic cylinder is a common important eq

Low temperature sintering of lead piezoelectric ceramicsThe binary system of lead zirconate titanate Pb (ZrxTi1-x) piezoelectric ceramics is prior for piezoelectric properties and temperature stability and Curie temperature piezo sphere transducer is greatly superior to other ceramics

The biggest feature of piezoelectric ceramicsThe biggest feature of piezoelectric ceramics is the positive and negative piezoelectricity. Positive piezoelectric vibration sensor means that under the action of mechanical external force, some dielectrics cause the rel
