The longitudinal piezoelectric ceramics strain constant d33 is the basic physical parameter of piezoelectric materials. It not only determines the properties of piezoelectric materials, but also directly affects the performance parameters of the transducer. In addition, other parameters, such as s

Due to many factors affecting the frequency and different application methods, we only provide the resonance frequency of piezoelectric ceramic plate as a reference under no-load condition. However, this resonance frequency, the natural frequency of piezoelectric ceramics,which can not be used as th

PZT piezoelectric ceramics have the characteristics of high curie temperature, strong piezoelectricity, easy doping modification and good stability. Since the 1960s, it has been a hot spot of attention and research, and it has dominated the field of piezoelectric ceramics. In terms of the preparatio

Piezoelectric ceramic resonators have a wide range of applications in many fields such as ultrasonic transducers, ceramic filters, piezoelectric accelerometers, and ceramic loudspeakers. In the traditional analysis and testing theory of piezoelectric ceramic resonators (including the international I

Sound wave is a kind of longitudinal wave that can be felt by the human ear. Its frequency range is 16Hz~2KHz. When the frequency of sound waves is lower than 16 Hz, it is called infrasound wave, and when it is higher than 2 kHz, it is called ultrasonic wave. Generally, sound waves are having a freq

The production and research of piezoelectric ceramic materials for high-power piezoelectric transformers In the research of piezoelectric ceramic materials, China's research is relatively backward. According to statistics, in the six years of 1997-2002, among the more than 60 patents published in Ch

their modulus of elasticity, and density and poisson's ratio of piezoelectric ceramics. What are the specific values?About piezoelectric ceramics, it is generally made of PZT-4 piezoelectric ceramic disc. Therefore, its elastic modulus is 7.65 × 10 ^ 10, and its density is 7.5 × 10 ^ 3. And its poi

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

When you are igniting a gas stove or water heater, there is a piezoelectric ceramic that has quietly served you once. In this type of piezoelectric ignition device, the manufacturer has a piezoelectric ceramic. When the user presses the spring of the ignition device, the transmission applies pressur

The piezoelectric ceramics vibrates under the action of an external alternating electric field to excite ultrasonic waves. The common vibration modes of piezoelectric ceramics are stretching vibration, bending vibration and shear vibration. The commonly used telescopic vibration modes of piezoelect
