| 摘要 |
A piezoelectric actuator module is proposed having one or a plurality of piezoelectric actuators which is or are clamped in between an actuator head and an actuator base. According to the invention, at least the piezoelectric actuator is provided with a protection layer system. Provision is made of at least one surrounding element for tightly fixing the protection layer system to the actuator head, to the actuator base and/or to the piezoelectric actuator. The at least one surrounding element is composed of a material having a shape memory and can be pressed onto the protection layer system after a mounting-dictated expansion.
