Six Factors we need to notice wave force of piezoelectric ceramic

1.Piezoelectric ceramics, can the voltage be generated to illuminate luminous diode or a flashlamp ?

The voltage of piezoelectric ceramics is generated is so small ,which can only reach the micro-ampere level, for the luminous diode or or a flashlamp ,its voltage and current is 2.5V/0.02A, so it can be seen that It is impossible.

2.Piezoelectric switches and piezoelectric ceramics, do these have something in common?

About piezoelectric ceramics and piezoelectric switches, these are something in common,  Because they are all the mutual conversion of pressure and electrical signals. However, piezoelectric ceramics convert electrical signals into pressure piezoelectric vibration sensor, and piezoelectric switches convert pressure into electrical signals.

3.About piezoelectric ceramic transducer, which is the effect of using piezoelectric ceramics?

About piezoelectric ceramic transducers, which utilize the two major effects of piezoelectric ceramics, in particular, the transducers use the inverse piezoelectric effect when they emit, and they utilize positive piezoelectric effect when is receiving ,In turn, let this kind of transducer work and use normally.

4.How is the detecting circuit of piezoelectric ceramic ?

The vibration detecting circuit of the piezo ceramic element is actually not complicated, you just connect the two electrodes on the oscilloscope. However, it should be noted that the voltage of the piezoceramic element chip is MV level. Also, if the signal amplitude is too low, a low-noise operational amplifier can be used to amplify the signal for observation.

5.What should be paid attention to during the welding process of piezoelectric ceramic ?

There are some precautions for the welding work of piezoelectric components sensor

.Specifically, it should not be too high in the welding time, it is not suitable for the process, otherwise it will affect the welding quality, and then affect the use of the piezoelectric ceramic sheet. The welding time is generally only a few seconds.

6.What is the relationship between the waveform and time of the piezoelectric ceramic  is generate electricity and the force?

 if it is the force of the periodic change and continues to act on the piezo ceramic sphere, then the piezoelectric ceramic will continue to generate electricity, and its waveform is close to sine wave. And if it is a momentary force, then it is close to the pulse on the waveform.
