Piezo element has internal electrode layer arranged between two adjacent piezoceramic layer elements, while piezo element comprises cross-section in one plane of electrode layer than in planes by adjacent piezoceramic layer elements

摘要

The piezo element (1) has a stack of multiple piezoceramic layer elements (3), and an internal electrode layer (7) arranged between two adjacent piezoceramic layer elements. The piezo element has cross-section in one plane of internal electrode layer than in planes by adjacent piezoceramic layer elements. The neighboring piezoceramic layer elements at the outer edges (13) to the intermediate inner electrode layer are chamfered. An independent claim is included for method for contacting piezo element.
