Abstract

L'invention porte sur une pluralité de dispositifs microélectromécaniques pouvant être facilement configurés pour imprimer un mouvement rotatif et/ou de translation à amplitudes étendues. Ces dispositifs comprennent un bloc fonctionnel microélectromécanique comprenant un élément pliable doté d'une première extrémité pouvant se raccorder à une structure de support, et un élément rigide droit doté d'une première extrémité raccordée à une seconde extrémité de l'élément pliable. Dans le cas où l'élément pliable est droit, l'élément rigide s'étend de la seconde extrémité de l'élément pliable à la structure de support. L'élément pliable a en outre une longueur prédéterminée, la longueur de l'élément rigide étant comprise dans une plage représentant de la moitié à la totalité de la longueur prédéterminée de l'élément pliable de sorte qu'une extrémité libre de l'élément rigide soit soumise à un mouvement rotatif et/ou de translation prolongé en réaction au déplacement de l'élément pliable. Les dispositifs microélectromécaniques de cette invention peuvent être utilisés comme actionneurs ou capteurs dans une variété d'applications microélectromécaniques et micro-opto-électromécaniques.
