Abstract
The piezoelectric behavior of Hydroxyapatite (HAp) composites by the mechanical action of high optical irradiances was studied. The piezoelectric and optical properties of HAp composites were considered based on previous researches. Using a finite method element and computational software, is obtained a numerical approximation of mechanical deformation by using a direct current voltage as input. It was considered a mechano-optical model to reproduce a normal force acting on the surface of the HAp composites provided by a nanosecond pulsed laser irradiation. The generated voltage was estimated under high optical irradiance using a proposed mathematical approach. This study can assist in the characterization of piezoelectric crystals by noninvasive disturbances. These results exposed the possibility of developing novel measurement procedures that involve nonlinear optical processes.
