| Abstract: | A new method for determining the piezoelectric constant d31 of piezoelectric materials was described. By contrast with common methods which measure d31 using standard samples, this new method use a practical sample—piezoelectric bimorphs. It were also provided the measuring principle, the measuring apparatus, etc., The theoretical and experimental results show that the new method is available. The measuring apparatus is simple, its price is lower, operation is easy, the precision is nigher. |
