ELECTROMECHANICAL CONVERTER COMPRISING A DUAL-LAYERED BASE ELEMENT, AND METHOD FOR PRODUCING SUCH AN ELECTROMECHANICAL CONVERTER

摘要

The invention relates to an electromechanical converter which comprises at least one polymer layer composite with cavities (5) designed therein, said polymer layer composite comprising at least one polymer layer base element (1) with a carrier layer (1a) that has a softening temperature TgA, and an electret layer (1b) with a softening temperature Tg E the surface of which is connected to said carrier layer, wherein Tg A > TgE, and - a second polymer layer element (2), the polymer layer base element (1) with its electret layer (1b) being at least partially connected to the second polymer layer element (2), with cavities (5) being formed. Moreover, the invention relates to a method for producing an electromechanical converter, for example a piezoelectric converter, and to the use of same.
