Abstract: A coupled mean field microelectromechanical model is developed as a predictive tool of the macroscopically observed piezoelectric material behavior. This model is used for studying the sensitivity of macroscopic foam behavior to various constituent material and void variables and it has improved the approximation of the true piezoelectret behavior.
