Abstract
(EN) A polymorphic surface may be provided by applying at least one magnetic field across a plurality of movable surface contour elements and selectively passing a current through the magnetic field(s) adjacent selected surface contour elements, with the current being perpendicular to the magnetic field. The current interacts with the magnetic field to generate a Lorentz force driving guided linear motion of the respective surface contour element(s). The surface contour elements may be individually moveable and individually selectable for application of current to generate movement. The surface contour elements may be supported in position after removing the current. The current applied across each selected surface contour element may be varied to control the amount of guided linear motion.
(FR) L'invention concerne une surface polymorphe susceptible d'être réalisée en appliquant au moins un champ magnétique aux bornes d'une pluralité d'éléments déplaçables de contour de surface et en faisant passer sélectivement un courant à travers le(s) champ(s) magnétique(s) au voisinage d'éléments sélectionnés de contour de surface, le courant étant perpendiculaire au champ magnétique. Le courant interagit avec le champ magnétique pour générer une force de Lorentz entraînant un mouvement linéaire guidé du ou des élément(s) considéré(s) de contour de surface. Les éléments de contour de surface peuvent être déplaçables individuellement et sélectionnables individuellement pour l'application du courant en vue de générer le mouvement. Les éléments de contour de surface peuvent être soutenus en position après la suppression du le courant. Il est possible de faire varier le courant appliqué aux bornes de chaque élément sélectionné de contour de surface pour réguler l'ampleur du mouvement linéaire guidé.
