Abstract
A ceramic piezoelectric, includes a thick core formed of a sintered ceramic material, and a pair of electrodes formed on opposing end faces of the core, wherein the electrodes are a reduced form of the ceramic material of the core. The electrodes may also be a reduced layer of an oxide formed on the ceramic material of the core.
