Factors to consider when it is designing the piezoelectric ceramic transducerThere are two main types of materials for ultrasonic transducers: magnetostrictive metals and piezoelectric ceramics. The purpose of this article is to design transducers for high-power mechanical ultrasoni

Explanation of vibration frequency of piezoelectric ceramicsFirst, the larger the piezoelectric ceramic area, the lower the natural vibration frequency.For the piezoelectric ceramic sensor,which pass through the related alternating current, it will produce a variety of different alternating current

1. What is the relationship between the thickness and frequency of a circular piezoelectric ceramic crystal?A circular piezoelectric ceramic crystal whose frequency mainly refers to the resonant frequency, and its resonant frequency has both radial and thick directions. For the radial resonant frequ

1. Piezoelectric ceramics, is the current generated by it being DC or AC? And, can it illuminate the LED?Piezoelectric ceramics, which generate the current, however, producing direct current, not alternating current. As for question two, the answer is no. Because the voltage and current generated by

1. About piezoelectric ceramics, what are the common applications?Common applications of piezoelectric ceramics, in general, applications for positive and negative piezoelectric effects, as well as piezoelectric ceramic buzzers, piezoelectric ceramic loudspeakers, piezoelectric ceramic pickups, piez

1. Piezoelectric ceramics, how can it be applied? And why do piezoelectric ceramics have to use ferroelectric materials?For piezoelectric ceramics, to make it useful, there must be a piezoelectric effect. Otherwise, it is no different from ordinary ceramics. As for piezoelectric ceramics, ferroelect

What’s piezoelectric sensor The piezoelectric ultrasonic sensor is based on the piezoelectric effect of some dielectric materials, and generates an electric charge on the surface of the dielectric under the action of an external force, thereby realizing non-electricity measurement. A piezoelectric s

The preparation process of alumina piezo ceramics mainly includes three aspects: preparation of alumina powder, formation of alumina ceramics and preparation of sintered alumina ceramics. At present, the preparation process of the alumina powder includes following aspects: (1) an hydrolysis method.

PZT piezoelectric element ceramic have conditions of dielectric constant and dielectric loss curve under the the temperature and frequency conversion. The temperature of dielectric constant can be seen. the dielectric constant increases very slowly which the temperature is below 250°C. That is, the
