Some geological materials such as quartz and biological materials such as cortical bones and cancellous bones exhibit piezo-electric behaviors, for which a mechanical wave such as ultrasound can trigger electro-magnetic waves. In this talk, we consider the porous composite materials made of linear piezo-electric solid with pores saturated with linear conducting fluid, a model that mimics in vivo bones. A focus of this talk is on the time domain well-posedness of this system of equations. The goal is to take the two-scale homogenization limit of this system in order to understand how the microstructures affect the effective properties of such porous piezoelectric composites.
