Abstract
In a method for producing a multilayer encapsulation () of a piezo actuator () such that the piezo actuator () is protected towards the outside without having to use an additional enveloping housing-type structure, in order to produce the multilayer encapsulation (), an electrically insulating elastic layer () is first applied to the surface of the piezo actuator (), whereupon a metallic layer is applied to the electrically insulating elastic layer () so as to planarly cover the same.
