| 摘要 |
The invention relates to an actuator body, comprising a plurality of piezoceramic layers, which are separated from each other by means of a positive or negative internal electrode in alternation, positive and negative collecting electrodes, which are arranged on two outer faces of the actuator body and are conductively connected to the associated positive or negative internal electrodes, wherein the actuator body of the multilayer actuator has at least one positive and one negative contacting electrode, by means of which the multilayer actuator is electrically contacted and which is conductively connected to the associated positive or negative collecting electrode, and the contacting electrodes are arranged in areas of the actuator body that are provided with a base metallization. The areas of the actuator body provided with a base metallization are spaced apart from each other and distances from the internal electrodes, wherein the distances are not less than the thickness of the piezoceramic layers in the active area of the multilayer actuator. |
