Abstract
An inertial piezoelectric device has: A) piezoelectric capacitor having a substrate; 2) a dry piezoelectric layer comprising a piezoelectric material; 3) a first electrode arranged contiguously with one opposing surface of the dry PL; and 4) a second electrode arranged contiguously with a second opposing surface of the first dry PL. The first dry electrically-conductive layer consists essentially of: (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 device also has B) signal processing electronics in electrical communication with the piezoelectric capacitor; C) a means for converting all or a portion of an applied force to an inertial force that is transmitted to the first dry PL; and optionally D) a proof mass that is contiguous with at least one external surface of the piezoelectric capacitor.
