    Abstract: The invention relates to a multilayer electrical component that has a plurality of ceramic layers arranged one on top of the other along a longitudinal axis, with electrode layers arranged therebetween, wherein a ceramic designed breach layer that is less stable than the ceramic layers when exposed to tensile stresses in the longitudinal direction is provided at least at one point along the longitudinal axis between two ceramic layers. The invention also relates to a layer stack from which the multilayer component may be produced. The reduced stability of the designed breach layers serves to prevent cracks from propagating in uncontrolled manner into the component.

    Abstract: The invention relates to a piezoelectric component having a stack (1) of piezoelectric layers (2) stacked on top of one another and electrode layers (3a, 3b) arranged between them, wherein the electrode layers (3a, 3b) have a middle segment (4) in the interior of the stack (1), as well as an end segment (6) delimited by the interior side of a vertical edge zone (5) of the stack (1), wherein the end segments (6) of the electrode layers (3a, 4b) are enclosed by a first piezoelectric material (7), whose relative expansion is less than the relative expansion of a second piezoelectric material (9), which is arranged in a middle region (8) between two adjacent electrode layers (3a, 3b). Furthermore, the invention relates to a method for the production of the piezoelectric component. The component according to the invention has the advantage that the mechanical stress in proximity to the ends of the internal electrodes is reduced, thereby improving the serviceable life of the component.

    Abstract: A piezoelectric component includes piezoelectric layers and electrode layers between at least some of the piezoelectric layers. The electrode layers define a middle segment in an interior of the piezoelectric layers and end segments located between ends of at least some of the electrode layers and an end of at least one of the piezoelectric layers. The piezoelectric layers include a first piezoelectric material at the end segments and a second piezoelectric material at the middle segment between electrode layers. The first piezoelectric material has a first expansion that is less than a second expansion of the second piezoelectric material.
