Abstract
The invention relates to an actuator device () comprising an active layer () having directly or indirectly a skin layer () on top that can be touched by when in use by a user. The configuration of the active layer () can controllably be changed in an extension direction (x, y), and the skin layer () comprises a plurality of elevations (E) and intermediate recesses (R). Due to its structure, the skin layer () does not hinder conformation changes of the active layer () in the extension direction, while it provides favorable tactile characteristics of the actuator device (). The active layer () may particularly comprise an electroactive polymer (EAP). The skin layer () may be composed of a plurality of grains isolated from each other, or it may comprise a thin surface layer () that is stiffer than the active layer ().
