Abstract
  • Piezoelectricity is the coupling of the quasi-static electrical and dynamic mechanical response of a material. The direct piezoelectric effect is the polarization of a material through the application of mechanical stress, while the converse effect is the mechanical deformation of a material when a electric field is applied. In one application, a potential difference applied across the material and impedance response measured. That response being dependent on the material properties. The question is, given an impedance response, can we recover the material parameters of a material that will produce it? In this work, we are interested in the characterization of the material parameters doping profile of a composite piezoelectric material. We do this through the implementation of a 3-D finite element analysis of the inverse problem in disc (literal)
