1.The piezoelectric constant is a parameter to measure the strength of the piezoelectric effect of the material, which is directly related to the sensitivity of the piezoelectric output.
2.The elastic constants and stiffness of the piezoelectric materials determine the inherent frequency and dynamic characteristics of device.
3.For a certain shape and size of the element, the inherent capacitance also affects the frequency limit of sensor.
4.The mechanical coupling coefficient is the mechanical coupling coefficient is an important parameter to measure the mechanical and electrical energy conversion efficiency.
5.The temperature of the material that begins to lose the property is called curie point temperature.
