When is faced with thousands of thermistor types, selection may cause considerable difficulties. In this technical article, I will introduce you to some important parameters to keep in mind when is choosing a thermistor, especially when you want to use two commonly used thermistor types for temperat

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

Hydrothermal preparation of thick films has many advantages:① This process is completed in the liquid phase at one time, and no later crystallization heat treatment is required, thus avoiding defects such as cracking, grain coarsening, reaction with the substrate or atmosphere that may be cause duri

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

Overview of piezoelectric ceramic transducersPiezoelectric ceramic transducer is composed of piezoelectric ceramic crystal and light and heavy two metals. After polarization treatment at a certain temperature, it has piezoelectric effect. Piezoelectric ceramic ultrasonic transducers have entered the
