We study theoretically the influence of the underlying domain microstructure on the electromechanical properties of ferroelectrics. Our calculations are based on a continuum approach that incorporates the long-range elastic and electrostatic interactions. The theory is used to simulate the piezoelectric properties of a two dimensional model ferroelectric crystal. Simulation results indicate that the electromechanical response of the ferroelectric is strongly dependent on the domain microsctructure, including domain walls. This is particularly true for the case when an electric field is applied along a non-polar direction.
