What are the problems about piezoelectric ceramics?

Piezoelectric ceramics is not only a kind of ceramics, the most important thing is that they play a vital role in the actual process of work, for some of the original equipment, so in the process of practical use of piezoelectric ceramics, there may be a lot of problems, is not known to everyone.

(1) Is direct current or alternating current generated by piezoelectric ceramics?

Piezoelectric ceramics produces is the direct current, not the alternating current (ac), and in practical work process of the piezoelectric ceramic, they themselves are also belong to a kind of inorganic piezoelectric ceramic materials, the material can be divided into the piezoelectric ceramic crystal materials or two piezoelectric crystal, piezoelectric ceramic is generally refers to refer to is a piezoelectric crystal, And piezoelectric ceramics are basically polycrystals, so you'll probably find out more about the answer to the whole question.

(2) What is the meaning of piezoelectric ceramics P8?

Piezoelectric ceramic P8 specifically refers to the maximum power of the ceramic, actually such a relatively has a variety of different levels of ceramics is basically, if it is the fourth level, so basically also is sending and receiving solid, if is the fifth level, will have more test drive, if is the sixth level have higher stability, If it is a seventh level, and there is a higher frequency, there will be a standard for the final naming specification.

(3) What is the voltage and current generated by the piezoelectric ceramics on the lighter?

If you have a piezoelectric ceramic on a cigarette lighter, which is basically deformed by an external force, it creates a voltage and a current in an instant, and their specific numbers are in the relative range of 4,000 to 6,000 volts.
