The principle of the piezoelectric effect of an ultrasonic piezoelectric ceramic sheet is that if pressure is applied to a piezoelectric material, it will generate a potential difference (called the positive piezoelectric effect), and if a voltage is applied, it will generate mechanical stress (call

1.One-way Piezoelectric sensor The structure of the piezoelectric ceramic cylinder is usually a load washer type. The figure shows a one-way piezoelectric sensor structure, which is composed of a base, a force transmitting upper cover, a chip electrode, a quartz wafer, an insulating member

(1)Oil bath polarization methodThe oil bath polarization method is a method in which a product such as methyl silicone oil is used as an insulating medium to polarize a product under a certain polarization electric field, temperature and time. Due to the wide temperature range, high dielectric stren

Sensitive materialSensitive materials are the core components of high-temperature thin-film sensors. Their chemical and electrical stability have a great influence on piezoelectric rings vibration sensor whether thin-film sensors can be used in harsh environments. The kinds of sensitive materials, t
