PIEZOELECTRIC MULTILAYER ACTUATOR

摘要

A piezoelectric multilayer actuator includes a stack of piezoelectric layers arranged one above another and first electrode layers and second electrode layers arranged alternately one above another between said piezoelectric layers. The electrode layers extend into the stack from a first and a second lateral face of the stack and overlapping in the stack. The first lateral face holds a first contact element in electrical contact with the first electrode layers and the second lateral face (5) holds a second contact element in electrical contact with the second electrode layers. The first and second contact elements each have a wire mesh, wherein at least one wire mesh has a twill-weave structure.
