Multilayer piezoelectric component has electrode layers near target rupture layers, spaced at preset distance from lateral borders of active region of stack, while remaining electrode layers are made to contact the lateral borders

摘要

The component has piezoelectric layers (4) arranged one above the other in an active region (10) with lateral borders (20,30), so as to form piezoelectric layer stack (1). Electrode layers (21-26,31-36) and target rupture layers (41-43) are arranged in piezoelectric layer stack. The electrode layers (22,24,26,31,34,35) near the target rupture layers, are spaced at preset distance (d) from lateral borders, while remaining electrode layers (21,23,25,32,33,36) are made to contact the lateral borders.
