ABSTRACT = {This paper employs the Direct Finite Element Squared (DFE<sup>2</sup>) method to develop Sparse Polynomial Chaos Expansions (SPCE) models for analyzing the electromechanical properties of multiscale piezoelectric structures. By incorporating variations in piezoelectric and elastic constants, the DFE<sup>2</sup> method is utilized to simulate the statistical characteristics—such as expected values and standard deviations—of electromechanical properties, including Mises stress, maximum in-plane principal strain, electric potential gradient, and electric potential, under varying parameters. This approach achieves a balance between computational efficiency and accuracy. Different SPCE models are used to investigate the influence of piezoelectric and elastic constants on multiscale piezoelectric materials. Additionally, the multiscale parameterization study investigates how microscale material properties affect the macroscopic response of these structures and materials.},
