<p>The component has a set of piezoelectric layers lying upon each other, and electrode layers situated between the piezoelectric layers. An absorption layer (4) is provided in the stack of piezoelectric layers for absorbing mechanical vibration energy, where the absorption layer is two to three times thicker than the piezoelectric layers. The absorption layer causes an interface effect for shock waves or vibration impulses, and contains metal, ceramic, organic/inorganic material and adhesive or thermosetting plastic.</p> |
