摘要： 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.

摘要： The invention relates to a high-lifting capacity piezoelectric actuator (1) comprising an piezoelectric layer (10) and a second layer (20) whose material gradient is directed to the thickness. An electric field produces different extension degrees in said piezoelectric layer (10) and in the second layer (30), thereby increasing the lifting capacity of the piezoelectric actuator (1) in combination with an impressed mechanical prestressing. The inventive piezoelectric actuator is used at a low voltage, for example, for bio and medical engineering (micropumps, microvalves), in industrial electronic engineering (pneumatic valves) and for microactuators and micromotors.

摘要： In the operation of piezoactuators of multilayer construction, during the polarizing or during the operation of the piezoactuator tears can arise, due to voltages, in the metallization strips that are attached to the actuator on the outside for contacting the electrode layers. It is inventively proposed to install electrically conductive contact lugs directly at the stack or on the metallization strips such that a laterally protruding region remains, so that, even given arising tears, these nevertheless extend in the protruding region of the contact lug, and the tears are electrically bridged. Electrical terminal elements are provided so as the project above or laterally at the contact lugs.

摘要： A storage element for a solid electrolyte battery is provided. The storage element has a main member having a porous matrix of sintered ceramic particles in which particles that are made of a metal and/or a metal oxide and jointly form a redox couple are embedded. Along a preferred direction, the storage element has a certain concentration gradient of the particles made of the metal and/or the metal oxide and/or a certain gradient of a pore density and/or a pore size, thereby allowing the diffusion behavior of oxygen ions within the main member to be controlled and thus the charge and discharge kinetics, the life and the capacity of the battery to be improved.
