Abstract

L'invention concerne un actionneur comportant une armature (6) dotée d'un orifice (7) et un polymère (1) fixé à l'armature (6). L'armature (6) est élastique et fait fonction de ressort, l'armature (6) et le polymère (1) formant ainsi une structure à ressorts antagonistes. Le matériau du polymère (1) et/ou de l'armature (6) est choisi de façon à pouvoir être influencé pour changer de dimensions physiques et / ou d'état de tension, le fait d'influencer le polymère (1) et/ou l'armature (6) amenant l'armature à effectuer un mouvement hors du plan.
