Abstract

Dispositivo óptico de control electrostático que presenta un estado de funcionamiento variable, en particular persiana o espejo, que comprende un soporte fijo (2) que incluye un substrato (3), constituido por una lámina de material transparente, por lo menos un primer electrodo (4) constituido por una película fina de material eléctricamente conductor, que es por lo menos parcialmente transparente y está aplicado a una cara de la lámina que forma el substrato (3), una película aislante dieléctrica o ferroeléctrica (5), aplicada sobre la película (4) que forma dicho primer electrodo, y un pétalo móvil (6) que comprende una fina película de material eléctricamente conductor, con solamente una parte extrema conectada rígidamente a dicha película aislante (5) y adaptada para asumir una primera condición de funcionamiento, en la cual se adhiere totalmente, por efecto electrostático, a dicha película aislante (5), cuando se aplica un voltaje eléctrico entre dicho primer electrodo (4) y dicho pétalo (6), de tal manera que se activa un primer estado de funcionamiento de dicho dispositivo óptico, y medios para la desviación de dicho pétalo electrostático (6) hacia una segunda posición de funcionamiento, en la cual se encuentra distanciado de dicho soporte fijo (2), cuando no se aplica voltaje entre dicho primer electrodo (4) y dicho pétalo (6), de tal manera que se active un segundo estado de funcionamiento de dicho dispositivo óptico, en el que dichos medios para la desviación del pétalo (6) hacia su segunda posición de funcionamiento están constituidos por un segundo soporte fijo (7), distanciado del primer soporte fijo (2) y que soporta el segundo electrodo (9), existiendo medios para la alimentación de un voltaje eléctrico entre dicho pétalo (6) y el segundo electrodo (9), de tal manera que se determine que dicho pétalo (6) se adhiera a dicho segundo soporte fijo (7) cuando la alimentación eléctrica entre el pétalo (6) y el primer electrodo (4) se interrumpe, caracterizado porquedicho segundo soporte fijo (7) está constituido por una lámina ortogonal con respecto a la lámina (3) que forma el primer soporte fijo (2), y porque el pétalo electrostático (6) está constituido por una película plegada de forma sin fin y aplanada para formar una doble capa, con un extremo (6a) anclado al primer soporte fijo (2) en un lado y al segundo soporte fijo (7) en el otro lado.
