Abstract
An electroactive elastomer converter is described comprising at least one electroactive elastomer layer (3) with a top side and underside and an electrically conductive electrode body (1′) that is two-dimensionally connected to the top side at least in regions. An electrically conductive electrode body (1′) is dimensionally connected in at least two regions to the underside. At least one electrode body (1′) in each case has an electrode surface facing the elastomer layer (3). At least one opening (2) is present to which an a two-dimensional region in which there is no two-dimensional bond between the elastomer layer (3) and the electrode body (1′). A compressible medium is provided in the area of the opening.

An electroactive elastomer converter comprising:
- at least one electroactive elastomer layer having a top side and underside and an electrically conductive electrode body connected in an area to the top side at least in regions, an electrically conductive electrode body connected in an area to the underside at least in regions, at least one electrode body including an electrode surface facing the elastomer layer with at least one opening including a two-dimensional region which is not bonded between the elastomer layer and the electrode body and into which the elastomer penetrates upon application of pressure thereto into the at least one opening and the at least one opening being bordered on one side by the elastomer layer with a gaseous compressible medium disposed in the at least one opening, and wherein the at least one opening facing the elastomer layer has a concave shape providing at least one recess in the electrode surface and each of the at least one recess and the elastomer layer encloses a gas-tight volume containing the gaseous compressible medium.
An electroactive elastomer converter comprising:
- at least one electroactive elastomer layer having a top side and underside and an electrically conductive electrode body connected in an area to the top side at least in regions, an electrically conductive electrode body connected in an area to the underside at least in regions, at least one electrode body including an electrode surface facing the elastomer layer with at least one opening including a two-dimensional region which is not bonded between the elastomer layer and the electrode body and into which the elastomer penetrates upon application of pressure thereto into the at least one opening and the at least one opening being bordered on one side by the elastomer layer with a gaseous compressible medium disposed in the at least one opening;
