Flexoelectricity is the generation of electric fields through strain gradients. It offers unconventional ways to enhance the electromechanical coupling response of piezoelectric materials and composites compared to the conventional piezoelectricity which is a coupling between strain and electric fields. While the factors that are crucial for designing and tailoring flexoelectric enhancement have been explored from a perspective of bulk-piezoelectric materials, the factors influencing flexoelectric enhancement in piezo-composites are scarcely explored. Here, we investigate two design proposals to introduce flexoelectric enhancement in lead-free piezocomposites using an advanced electro-elastic model that incorporates piezoelectric and flexoelectric couplings. The first idea involves introducing anisotropy into the composite structure through a graded inclusion concentration. The second idea involves introducing porosity in the matrix to create structural anisotropy. We show that both of these strategies are capable of generating significant size-dependent flexoelectric enhancements. In summary, this investigation paves a way for newer manufacturing-compatible techniques to optimize the performance of the functional electro-elastic composite materials that are crucial for lead-free and environmentally friendly technologies.
