Actuating member and method for producing the same
First Claim
1. An actuating member with a body of elastomer material, which body on each of two boundary surfaces lying oppositely to one another is provided with an electrode arrangement, characterized in that at least one boundary surface (3, 4) has a waved area with heights (13) and depths (14) as extreme values running parallel to the transverse direction of the body, which waved area is covered by an electrode (5, 6), which electrode covers the full surface of at least a portion of the extremes (13, 14) and is continuous over the waved area.

Abstract
The invention relates to anactuating member comprising an elastomer body that is provided with one electrode each on opposite peripheries. The aim of the invention is to improve the dynamism of such an actuating member. To this end, at least one periphery is provided with at least one waved section that comprises elevations and depressions as the extremes disposed in parallel to the cross direction. Said section is covered by an electrode that completely covers at least a part of the extremes and that extends across the waved section.

- 9. A method for making an actuating member with a body of elastomer material which body is provided with electrodes on two sides lying oppositely to one another, characterized in that an elastomer is pressed into a mold (7) with a waved surface profile (8) to form a film (9), which film is then left to harden for so short a time that it remains formable, then a further mold (10) with a waved surface (11) is pressed against the other side of the film (9), and after the forming of the outer surface structure a conducting layer is applied to the outer surface.
