Abstract
The present invention relates to electromechanical converters at least comprising a polymer layer composite with voids (5) formed therein, wherein the polymer layer composite at least comprises
- a polymer layer base element (1) comprising a carrier layer (1a) having a softening temperature TgA and en electret layer (1b), extensively bonded thereto, having a softening temperature TgE, wherein TgA>TgE, anda second polymer layer element (2), whereinthe polymer layer base element (1) is at least partially bonded with its electret layer (1b) to the second polymer layer element (2) to form voids (5). The invention relates further to a process for the production of an electromechanical, for example piezoelectric, converter and to the use thereof.
