Abstract
An example flexoelectric piezoelectric composite has a piezoelectric response, which may be a direct piezoelectric effect, a converse piezoelectric effect, both effects, or only one effect. The flexoelectric composite comprises a first material, which may be substantially isotropic, the first material being present in a shaped form. The shaped form gives a piezoelectric response due to a flexoelectric effect in the first material. The shaped form may have ∞m symmetry, or a polar variant of this form such as 4 mm symmetry.
