Abstract

Piezoelectric composites with 1-3 connectivity have been widely studied due to their practical applications to biomedical imaging, ultrasound therapy and bone tissue engineering. They are flexible to conform to curved surfaces and their electromechanical properties and performance can be tailored for specific applications. In this research work, a multi-step micromechanics based Mori-Tanaka model for piezoelectric composite is developed to study the effective performances of 1-3 piezoelectric composites with piezoceramic fibers embedded in porous piezoelectric and non-piezoelectric matrices. The porous matrix is first homogenized using the Mori-Tanaka model, and then the porous matrix with piezoelectric fibers is homogenized using the Mori-Tanaka method for piezoelectric. The present work focuses on the performances of composites using various types of piezoelectric and non-piezoelectric materials for bone tissue engineering applications. Results of the studies show that the piezoelectric composite performances are largely dependent on the fiber volume fraction and that the presence of porosity further improved the performance of the composites.
