Abstract

L'invention porte sur des actionneurs électro-actifs et sur leur procédé de fabrication. Lesdits actionneurs consistent en une couche s'étendant longitudinalement d'un matériau électro-actif recourbé de manière à former une ligne ou un dessin non rectiligne de courbure uniforme ou non uniforme et présentant une section dont le rapport (r/t) rayon de courbure moyen sur épaisseur est voisin de 0,5. Ladite couche, de préférence monolithique, ne comporte pas de couche électrode enfouie, ce qui en facilite la fabrication.
