ISO 9001 Certification Piezo Ceramic Positive And Negative Electrode in Different suface
Piezoelectric ceramic materials are electromechanical transducers: They can convert mechanical energy into electrical energy and vice-versa.  Piezoelectric ceramic material from us are used in sensors, actuators, gas ignition and in power transducers for high-power ultrasonic applications.
Piezoelectric ceramic  Material are used to convert mechanical parameters, such as pressure and acceleration, into electrical parameters or, conversely, to convert electrical signals into mechanical movement or vibration.
In sensors they make it possible to convert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers to convert electric voltages into vibrations or deformations.

Acoustic waves are the form of propagation of the mechanical vibration state (or energy) of an object. Ultrasound refers to the vibration frequency is greater than 20000Hz above, its frequency of vibration per second (frequency) is very high, beyond the general limit of human hearing (20000Hz), people will call this inaudible sound waves called ultrasound. Because of its high frequency, it has many characteristics: First, it has a large power, and its energy is much larger than the general sound wave, so it can be used for cutting, welding, drilling and so on. Furthermore, because of its high frequency, short wavelength, and poor diffraction, it has good directionality, and ultrasound is commonly used in industrial and medical applications for ultrasonic detection. [1] Ultrasound and audible sound are essentially the same. Their common point is a kind of mechanical vibration mode. It usually propagates in the elastic medium in the form of longitudinal waves. It is a form of energy transmission. Its difference is Ultrasonic frequency is high, the wavelength is short, and it has good beam directionality and directivity in a straight line within a certain distance, 1 megahertz=10^6Hz, ie each

The second vibration is 1 million times, and the frequency of the audible wave is between 16-20000HZ).



1.The frequency limit of apiezoceramic sheet and some properties?

Usually the frequency limits of applications are ascertained through the resonances involved with the transducer design and its size and shape. For a piezoceramic sheet, there is no limit for inherent frequency. A sheet of PSI-5A material which is 2.85″ square, .0075″ thick has planar dilatation mode of about 14 KHz and of 13 MHz of thickness mode vibration in the neighborhood. Limiting factors can arise such as the resistive heating of electrodes when considerable current is gathered at large surface area parts during ultrasonic frequencies.

2.Is there any truth to piezo transducers being used as static and dynamic force sensors?

Due to charge leakage the Piezo transducers cannot be used for static force measurements. For transient force measurements they can be applied successfully for only0.1 second.
3.The expected life of piezoelectric material?
There are no tests yet that can determine the “fatigue life”. Our facility has had an operational piezo fan since 1982. Such calculations must involve voltages and mounting.
4.How does temperature effectpiezoceramic transducers?
The pyroelectric properties of piezoceramic are responsible for the appearance of voltage through the any piezo transducer electrodes due to temperature changes. Almost each and every property of piezoceramics is affected by temperature. There exists no general manner regarding it. In accordance to your experiment and calculations, the dependence must be looked upon in that context.
