Abstract

This paper describes the effective electromechanical properties of hydroxyapatite-BaTiO3 0-3 composites as a potential bone substitute material. The permittivity, d(3j) and g(3j) piezoelectric coefficients are calculated for composites at a range of compositions and connectivities to understand the relationships between composite composition and piezoelectric and dielectric properties. The properties of the composites can be tailored by adjusting the volume fraction and aspect ratio of the BaTio(3) particles and the shape and level of porosity in the hydroxyapatite matrix.
