Claim Text:
1. An electroactive polymer stack, comprising: a spirally wound strip, the strip having a planar surface extending in a length and a width, the length being larger than the width, and the strip further having a thickness which is smaller than the length and the width, the strip being wound about a center axis in such a way that the width of the planar surface extends in a direction perpendicular to the center axis, wherein the strip has one layer of an electroactive polymer and planar electrodes applied to sections of the electroactive polymer layer, and wherein multiple planar electrodes which do not directly adjoin each other on the strip prior to being wound are congruently situated on top of each other after being wound, in each case two planar electrodes which are situated on top of each other being separated from each other by at least one layer of the electroactive polymer.
