    • The present invention relates to a method for producing two- or multi-layer ferroelectrets with defined voids, with the exception of three-layer ferroelectrets with a perforated middle layer made of PTFE between two FEP layers, involving, introducing one or more clearances into at least one surface side of a polymer film element by means of a method of removal, applying a first covering to the surface side of the polymer film element comprising clearances formed in step A), and joining the polymer film element and the covering to form a polymer film composite, the clearances being closed while voids are formed, and to a two- or multi-layer ferroelectret, with the exception of three-layer ferroelectrets with a perforated middle layer made of PTFE between two FFP layers, in particular produced by this method. The invention also relates to a piezoelectric element containing a ferroelectret multi-layer composite according to the invention.
