The electronic thermometer consists of a temperature sensor, a liquid crystal display, a button battery, an ASIC and other electronic component piezo sounder ceramic element . It can quickly and accurately measure the body temperature of human body. Compared with the traditional mercury glass thermo

The piezoelectric ceramic element in the ultrasonic beauty instrument refers to a mechanical vibration wave whose frequency exceeds 20,000 Hz and cannot cause normal human hearing, and the vibration wave has mechanical action, warming action and chemical action. The ultrasonic beauty instrument util

The ultrasonic atomizer uses electronic high-frequency oscillation (oscillation frequency is 1.7MHz or 2.4MHz, which exceeds the human hearing range, the electronic oscillation is harmless to humans and animals), and the liquid water molecules are passed through the high-frequency resonance of the p

The piezoelectric effect is that when some dielectrics are deformed by an external force in a certain direction, polarization occurs inside, and positive and negative opposite charges appear on the two opposite surfaces thereof. When the external force is removed, it will return to the uncharged sta

(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

Whether the polarization process of piezo ceramic is sufficient or not has a great influence on the material properties. Therefore, it is necessary to reasonably select the polarization conditions, the polarization electric field, the polarization temperature and the polarization time, which are ref

Domain:Generally, the directions of spontaneous polarization of ferroelectrics are different, but in a small area, the spontaneous polarization directions of the respective unit cells are the same, and this small area is called a ferroelectric domain. The boundary wall between the two domains is cal

1)Research status of high temperature piezoelectric materials: SiO2 is one of the earliest piezoelectric materials applied to devices.
