Abstract
A piezoelectric component includes at least one monolithic piezo element, having at least a first electrode layer, at least a second electrode layer and at least one piezoceramic layer located between the electrode layers. The piezoelectric component is characterized in that at least between one of the electrode layers and the piezoceramic layer is provided an uncoupling layer which is in direct contact with at least one of the layers for mechanically uncoupling the electrode layer and the piezoceramic layer. A method for producing such a piezoelectric component is disclosed. The piezoelectric component is used in automotive technique for controlling an internal combustion engine injection valve.
