Title
(EN) FIVE DEGREES OF FREEDOM MEMS ACTUATOR FOR AUTOFOCUS, OPTICAL IMAGE STABILIZATION, AND SUPER RESOLUTION IMAGING IN MINIATURE CAMERAS
(FR) ACTIONNEUR MEMS À CINQ DEGRÉS DE LIBERTÉ POUR LA MISE AU POINT AUTOMATIQUE, LA STABILISATION D'IMAGE OPTIQUE ET L'ACQUISITION D'IMAGES À SUPER-RÉSOLUTION DANS DES CAMÉRAS MINIATURES
Abstract
(EN)
A MEMS electrostatic actuator that provides 5 degrees of freedom (5-DOF) motion is disclosed. The actuator comprises of an inner, a middle, and an outer MEMS structures that are nested with respect to each other. Each of the structures comprise of a plurality of rotors and stators. The rotors further comprise a plurality of moving capacitive electrodes which engage with a plurality of fixed capacitive electrodes in the stators to provide a variety of translational and rotational motions.

L'invention concerne un actionneur électrostatique MEMS fournissant un mouvement à 5 degrés de liberté (5-DOF). L'actionneur comprend une structure interne, une partie intermédiaire et une structure MEMS externe qui sont imbriquées l'une par rapport à l'autre. Chacune des structures comprend une pluralité de rotors et de stators. Les rotors comprennent en outre une pluralité d'électrodes capacitives mobiles qui viennent en prise avec une pluralité d'électrodes capacitives fixes dans les stators pour fournir une variété de mouvements de translation et de rotation.
