Abstract

Un dispositif de commutateur MEMS est réalisé en utilisant un alliage d'or en tant que matériau de contact de commutateur. L'augmentation de la dureté mécanique de l'alliage comparée à celle à l'or pur évite que les contacts du commutateur ne se soudent les uns aux autres. Une action de nettoyage qui a lieu lorsque le commutateur se ferme peut permettre aux surfaces de contact de venir en appui là où leurs surfaces sont complémentaires, résultant ainsi en une zone de contact plus grande et en une faible résistance de contact, malgré la résistance de feuille de l'alliage d'or plus élevée que celle de l'or pur.
