Abstract

Un appareil de vibration fluide et une méthode pour le piloter. L’appareil (1) ayant deux chambres de fluide ou plus comprend des diaphragmes (3) et (4) formant au moins un partie des chambres de fluides (7) et (8). Les diaphragms (3) et (4) contiennent des membranes conductives à haute molécularité et une électrolyte est remplie dans un espace clos (9) faisant face aux deux (ou plus) diagrammes (3) et (4). Les diaphragmes (3) et (4) comprennent les chambres de fluides sur les côtés opposés à l’espace clos (9) à travers les diaphragmes (3) et (4), et contient la membrane à haute molécularité de telle sorte qu’elle soit en contact avec l’électrolyte.
