PIEZOCERAMIC MULTILAYER ACTUATOR, METHOD FOR PRODUCING A PIEZOCERAMIC MULTILAYER ACTUATOR, AND INJECTION SYSTEM

摘要

A piezoceramic multilayer actuator has at least one outer electrode which can expand and provides at least two current paths between a supply potential connecting area of the outer electrode and a respective inner electrode, with which the outer electrode makes contact, of a piezo-stack of the multilayer actuator.
