Since 1880, French physicists P. Curie and J. Curie have discovered the Piezoelectric effect piezo element.The current piezoelectric effect materials can be roughly divided into three categories,it is piezoelectric single crystals, including ferroelectric Piezoelectric discs transducer,non-ferroelec

What are the distance methods for ultrasonic distance transducer?In the ultrasonic distance transducer,distance methods generally have a single-shot dual-receiving type, and it is also a sonic logging method. In terms of composition, there are mainly three sound systems, sound insulators and electro

Piezo sounder ceramic element is a piezoelectric ceramic that can vibrate and sing under the excitation of an alternating electric field after being bonded to a metal substrate. However, because the acoustic impedance of the air does not match, the sound emitted is very small; the high-decibel buzze

1.About the piezoelectric ceramic materials, can their parameters be varying?As for the piezoelectric ceramic materials, in general, whose parameters are constant rather than changing conditions. However, it should be noted that the thickness and diameter of the piezoelectric ceramic have a certain
