Abstract
A composite article has 1) a dry piezoelectric layer comprising a piezoelectric material, 2) a dry dielectric layer arranged contiguously with at least one of the opposing surfaces of the dry piezoelectric layer, and 3) a pair of non-electrically-connected co-planar patterned electrodes. The dry dielectric layer has essentially (a′) a dielectric material; and (b) particles having a Young's modulus that is different from the Young's modulus of the (a′) dielectric material by at least 10%.
