Description
Technical field

Background technology
Some electrolyte go up in a certain direction deformed by the effect of external force time, can produce polarization phenomena inside it, positive and negative contrary electric charge occur on its two apparent surfaces simultaneously.After external force is removed, it can return to again uncharged state, and this phenomenon is referred to as direct piezoelectric effect.Piezoelectric effect refers to produce under the most stressed effect of crystal bound charge, and bound charge is in proportion (i.e. direct piezoelectric effect) or the phenomenon of generation mechanical deformation (i.e. inverse piezoelectric effect) under the effect of extra electric field with impressed pressure.The material with piezoelectric effect is referred to as piezoelectric, and ferroelectric material belongs to the one of piezoelectric.Electric charge that piezoelectric produces under unit pressure effect or the deformation quantity produced under unit voltage effect are referred to as piezoelectric modulus, are used for weighing the size of piezoelectric effect.Owing to piezoelectric achieves machine-electric coupling character, various piezo-electric type device can be prepared hence with piezoelectric, such as high frequency and microwave piezoelectric transducer, piezoelectric oscillator, piezoelectric filter, piezoelectric transducer, piezoelectricity SAW device and nonlinear device etc., these devices are increasingly extensive in the application of military, business and civil area.
When using the piezoelectric modulus that direct piezoelectric effect measures piezoelectric, the two of measured material end faces are prepared electrode, material applies pressure, measures the electric charge produced on electrode, obtain piezoelectric modulus.Such as, Vertical loading method, air pressure platform method are all to utilize direct piezoelectric effect to measure piezoelectric modulus.These methods, while relatively simple, but precision is the highest, more can not characterize the piezoelectric property of material domain, and currently used is little.Use inverse piezoelectric effect to measure piezoelectric modulus, the two of measured material end faces are prepared electrode, apply voltage by electrode to material, measure the deformation of material, obtain piezoelectric modulus.The inverse piezoelectric effect mainly system of testing is utilized to have laser interferometer piezoelectricity test system, scanning near-field microwave microscopy test system.
Traditional piezoelectric element piezoelectric property evaluation mainly carries out piezoelectric element selection by material property parameter and structural behaviour parameter etc., but this kind of method influence factor is more, and there is cross influence relation, judgment criteria is the most directly perceived, less with actual application environment relatedness, it is primarily present following shortcoming: 1, piezoelectric element basic material index of correlation test instrunment is expensive, operation complexity, and mostly single parameter can only be tested, and piezoelectric to refer to index more, between each parameter, the relation of influencing each other can not intuitively characterize, and judgment criteria is unreasonable.2, the material property of piezoelectric element is affected by its processing technique, polarization condition etc., and its made piezoelectric element performance is bad.
