Yderelektrode til monolitisk flerlaget aktuator

摘要

The piezoceramic actuator has a sintered stack of thin-foil piezoceramic layers alternating with inner electrode layers (3), extending inwards from opposite sides of the stack and connected in parallel via outer electrodes, provided by respective metallisations (4) applied to the contact sides of the stack, with soldered terminal elements (5). A three-dimensional structured conductive electrode (6) is provided between the metallisation and the soldered terminal element and connected to the metallisation via discrete contact points (7) between which it is expandable.
