Abstract
A piezoelectric capacitor includes A) a composite article that has 1) a dry piezoelectric layer (dry PL); 2) a first dry electrode comprising a dry electrically-conductive layer arranged contiguously with a first opposing surface of the dry PL; and 3) a second dry electrode arranged contiguously with a second opposing surface of the dry PL. The dry electrically-conductive layer has essentially (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%. The capacitor also has B) electrical communication means attached to both electrodes for electrical communication of the composite article with an external electrical circuit.
