Abstract
The invention relates to a piezoelectric multiple-layer component with a base body, which comprises a stack of piezoelectric layers (5) lying one above the other and electrode layers (3, 4) lying in-between, wherein an electrically conductive contact element (1, 2), which comprises a porous material and which contacts the electrode layers, extends transverse to the electrode layers (3, 4).
Claims26
A multiple-layer component comprising:
- at least two metal layers;
- at least one dielectric layer among the at least two metal layers;
- a contact element comprising a porous body that electrically connects the at least two metal layers.
Dependencies are inferred from the claim text.
