Determination of the PIC700 Ceramic’s Complex Piezo-Dielectric and Elastic Matrices from Manageable Aspect Ratio Resonators
Achieving good piezoelectric properties, such as the widely reported d(33) charge coefficient, is a good starting point in establishing the potential applicability of piezoceramics.

description | Achieving good piezoelectric properties, such as the widely reported d(33) charge coefficient, is a good starting point in establishing the potential applicability of piezoceramics. However, piezoceramics are only completely characterized by consistent piezoelectric-elastic-dielectric material coefficient matrices in complex form, i.e., including all losses. These matrices, which define the various alternative forms of the constitutive equations of piezoelectricity, are required for reliable virtual prototyping in the design of new devices. To meet this need, ten precise and accurate piezoelectric dielectric and elastic coefficients of the material, including all losses, must be determined for each alternative. Due to the difficulties arising from the coupling of modes when using the resonance method, this complete set of parameters is scarcely reported. Bi(0.5)Na(0.5)TiO(3)-based solid solutions are already commercially available in Europe and Japan. Here, we report a case study of the determination of these sets of material coefficients (d(iα), g(iα), e(iα) and h(iα); s(E)(,D)(αβ) and c(E)(,D)(αβ); ε(T)(ik) and ε(S)(ik); and β(T)(ik) and β(S)(ik)), including all losses, of the commercial PIC700 eco-piezoceramic. Plate, disk, and cylinder ceramic resonators of a manageable aspect ratio were used to obtain all the material coefficients. The validation procedure of the matrices is also given by FEA modeling of the considered resonators. |
