Abstract
A composite article has 1) a dry piezoelectric layer, and 2) a pair of non-electrically-connected co-planar patterned electrodes that are arranged contiguously with an opposing surface of the dry piezoelectric layer. Each electrode essentially has (a) an electrically-conductive material; and (b) particles having a Young's modulus that is different from the Young's modulus of the (a) electrically-conductive material by at least 10%.
