Title
(EN) ELECTROSTATIC/PNEUMATIC ACTUATORS FOR ACTIVE SURFACES
(FR) DISPOSITIFS D'ACTIONNEMENT ELECTROSTATIQUE/PNEUMATIQUE POUR SURFACES ACTIVES
Abstract
(EN)
An actuator device providing an active surface. The actuator has a base (23) having at least one first electrostatic electrode mounted therein which is oriented for electrostatic cooperative action with an opposing electrostatic electrode in a cover (25) mounted above the first electrostatic electrode to define an enclosed cavity. The cover (25) has at least one second electrostatic electrode for cooperative electrostatic activation between the electrostatic electrodes. The cover (25) also has an outer surface forming the active surface. A power supply is operably connected to the electrostatic electrodes for causing the cooperative electrostatic activation. A quantity of fluid is contained within the cavity for pneumatically defining active surface conditions during cooperative electrostatic actuation. The cavity may be closed to provide a sealed cavity for movement of the fluid, either a gas or a liquid, during the cooperative electrostatic actuation, or it may be open to the atmosphere. The electrostatic electrodes may comprise a plurality of electrostatic electrodes arranged in a pattern to cause a predetermined change in the active surface. Various patterns may be used, such as bands, patches and regions. Also provided is control electronics in the base for controlling application of power from the power supply.

L'invention concerne un dispositif d'actionnement fournissant une surface active. Ce dispositif d'actionnement présente une base (23) sur laquelle au moins une première électrode est montée, cette dernière étant destinée à collaborer de manière électrostatique avec une électrode électrostatique opposée placée dans une protection (25) appliquée sur la seconde électrode électrostatique de manière à définir une cavité fermée. La protection (25) présente au moins une seconde électrode électrostatique destinée à collaborer de manière électrostatique entre les électrodes électrostatiques ainsi qu'une surface extérieure formant la surface active. Une source d'alimentation est reliée de manière opérationnelle aux électrodes électrostatiques de sorte à assurer une collaboration électrostatique. Une quantité de fluide est contenue dans la cavité permettant de définir de manière pneumatique des conditions de surface active au cours de la collaboration électrostatique. La cavité peut être fermée pour assurer l'étanchéité au mouvement du fluide, un gaz ou un liquide, pendant la collaboration électrostatique ou elle peut être ouverte à l'air libre. Les électrodes électrostatiques peuvent comprendre une pluralité d'électrodes électrostatiques disposées dans un modèle de manière à modifier la surface active selon des paramètres prédéfinis. Différents modèles peuvent être utilisés, à savoir des bandes, des pastilles et des zones. L'invention concerne également une commande électronique destinée à commander l'application de tension en provenance de la source d'alimentation.
