What is piezoelectric ceramicPiezoelectric ceramics is an information function PZT material piezo ceramic that can convert mechanical energy and electrical energy to each other-piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties and elasticit

Piezoelectric materials are functional materials that realize the conversion between mechanical energy and electrical energy. Its development has a long history. Since the discovery of the piezoelectric effect on quartz crystals by the CURIE brothers in the 1880s, piezoelectric materials have attrac

What is the piezoelectric effectAbout piezoelectric effect,When a certain dielectric is deformed by an external force in a certain direction, polarization will occur inside it, and positive and negative charges will appear on its two opposite surfaces. When the external force is removed, it will ret

Parameters of piezoelectric materials and piezoelectric equations (3)(11)Mechanical quality factor QmWhen the PZT material piezo ceramic is used for resonance vibration, it is necessary to overcome the internal mechanical friction loss (internal consumption), and when there is a load, it is necessar

Piezoelectric ceramic is a polycrystalline film with piezoelectric effect, and its production process is named after its similar production process (raw material pulverization, molding, high temperature sintering). Some anisotropic piezo crystals undergo deformation under mechanical force, causing t
