In the special piezo ceramic industry, there are also some "flavoring agents". Although the amount added in the piezo ceramic formula is very small, it has a very important role in improving the processing performance of special piezo ceramics and improving the performance of special ceramic product

Second, the piezoelectric parameters3. There is a complicated relationship between the piezoelectric parameters of piezoelectric materials, such as e = dE and E = -he as described above. Comparing them seems to give d = -1 / h, but it is not true in practice. Because the former is given under the co

The development history and characteristics of ultrasoundAcoustics, as a branch of physics,it is a science that studies the occurrence, propagation, reception, and effects of sound waves. Before 1940, there were only single-crystal piezoelectric materials, which made ultrasonic wave not widely used.

Piezoelectric ceramic micro-actuators are new type solid-state actuators made using the inverse piezoelectric effect. They are widely used in high tech fields such as precision optics, micromechanics, microelectronics, and computer applications. These applications require piezoelectric ceramic devic

The transducer array are the key components in the sonar system. It is a device that realizes the mutual conversion of electro-acoustic energy. The performance of the transducer and the transducer array mainly depends on the performance, structure and manufacturing process of the transducing materia

1. Piezoelectric ceramic transducer, how to say specifically?Piezoelectric ceramic sheet, which is a kind of electronic sounding component from a professional point of view, dielectric material of piezo ceramic ring is placed in the two copper circular electrodes, and an AC audio signal is connected

Ultrasonic cleaning machines are now used in people's lives, washing dishes, industrial cleaning, etc. Ultrasonic cleaning greatly reduces labor costs, but when people buy ultrasonic cleaning machines, the performance of ultrasonic cleaning machines.There are still some ambiguous knowledge: the larg

Piezoelectric ultrasonic transducer means that the vibration frequency is greater than 20KHz, and the number of vibrations per second (frequency) is very high, which exceeds the upper limit of the human ear (20000Hz). People call this inaudible sound wave ultrasonic. Ultrasound and audible sound are

Piezoelectric ceramics can produce electrostrictive effects under the action of alternating electric field. Piezoelectric ceramic ultrasonic transducers can generate vibration under the action of alternating electric field, and can generate strong ultrasonic waves during resonance. Since piezoelectr
