Abstract
A composite article useful in various electronic devices has 1) a dry piezoelectric layer (first dry PL) comprising a piezoelectric material, and 2) one or more dry dielectric layers arranged contiguously with opposing surfaces of the first dry PL. 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%. The (b) particles have a d50 of at least 500 nm and up to and including 500 m and a polydispersity coefficient that is less than or equal to 3, provided that the weight ratio of the (b) particles to the (a′) dielectric material is at least 0.01:1 and up to and including 10:1.
