Abstract

Biomedical transducers widely employ piezoceramic polymer composites with 1-3 connectivity. The research is aimed at determining the effective material properties of these composites in the micrometer scale by simulation. Volume fraction of piezoceramic in the composite plays an important role in composite material properties as studied by several researchers. It is also noted that the ber aspect ratio (a=l) also affects the composite material properties. Therefore it is intended to determine the effective material properties both analytically and by simulation using computer simulation software program ANSYS which implements nite element method (FEM). In the present work piezoelectric ber composites are modeled, analyzed and then the results are veried by using analytical equations. Important conclusions are drawn to select the piezocomposite materials for transducer applications.
