Abstract
An EAP generator is described, including at least one EAP stack that is disposed between two force-transferring surfaces disposed parallel to one another, having at least one layer, facilitating relative displacement between the end of the EAP stack and the force-transferring surface facing toward that end, in particular a deformable or friction-reducing intermediate layer. A corresponding method for generating electrical energy from elongation energy on a capacitive basis by charge displacement is also described.
