ABSTRACT:
A device with a piezoelectric actuator (1) comprises two faces (2, 3) and two electroconductive contact paths (4, 5), each traversing the actuator (1) starting from at least one face (3). The actuator is clamped between two metallic plates (6, 7), each arranged against a face (2, 3). The piezoelectric actuator further comprises an electroinsulating layer (8) arranged between each face92, 3) and the corresponding metallic plate (6, 7).
