Abstract

A method for electrically contacting a piezoelectric ceramic includes: providing the piezoelectric ceramic having electrodes for electrically contacting the piezoelectric ceramic and having a flexible, electrically conductive film; producing a composite by applying the flexible, electrically conductive film at least partially to an electrode of the piezoelectric ceramic; forming a durable, electrically conductive connection between the flexible, electrically conductive film and the electrode of the piezoelectric ceramic. Also a sound transducer, as well as a sound transducer array produced using the method for electrically contacting a piezoelectric ceramic.
