Abstract: The embodiments relate to a piezoelectric component including at least one fully active piezoelectric element comprising electrode layers and piezoelectric layers arranged therebetween. The electrode layers are conveyed to a lateral edge of the piezoelectric element and contacted there. The external electrode is attached in a structured fashion for electrical contacting and/or a structured external electrode is made available: The external electrode essentially includes two components, namely the contacting field and the contacting path. In the event of several piezoelectric elements (piezoelectric actuator in multilayer structure) stacked one above the other, the contacting path functions as a collector electrode, which connects the contacting fields of the piezoelectric elements to one another. The insulation path exists for the electrical insulation of the contacting path from electrode layers which are not to be contacted.

Abstract: A piezoelectric component with at least one fully active piezoelement has electrode layers and interposed piezoelectric layers guided to a lateral edge of the piezoelement and contacted there. An insulating layer applied for electric contacting has an electric through-plating. An electrically conductive gas-phase deposition layer is applied directly to the electrode layer guided up to the lateral surface of the piezoelement by way of deposition from the gas phase in order to improve electric contacting. An external electrode is applied to the gas-phase deposition layer. In the case of several superposed stacked piezoelements (piezoactuator in multi-layer design), the external electrode functions as a collector electrode which connects the electrode layers to each other. The structure enables secure contacting of the electrode layers. A fully active piezoceramic multi-layer actuator with the described contacting may be used in automobile technology for activating fuel-injection valves.
