Abstract

Actionneurs piézoélectriques à déformation amplifiée L’invention concerne un actionneur électromécaniqueà déformation amplifiée, comportant au moins un élément moteur (21) connecté à une source de tension sinusoïdale de façon à produire une déformation dudit élément moteur, caractérisé en ce qu’il comporte une masselotte ou plaque(22) dont une première face est fixée de façon rigide à l’élément moteur (21) et dont la face opposée est fixée à un support (40) à actionner, et en ce que ladite masselotte ou plaque(22) est configurée de manière que l’amplitude de la vibration transmise par la masselotte ou plaque(22) au support ou surface (40) soit supérieure à l’amplitude de la vibration générée par l’élément moteur (21) seul en l’absence de la masselotte ou plaque(22).
