Abstract

L'invention concerne un actionneur qui combine des aimants (202,204,206) avec des élastomères diélectriques (208). Une ou plusieurs forces magnétiques d'attraction ou de répulsion peuvent être déployées. Ce nouvel actionneur permet d'obtenir des efforts importants et des forces plus élevées qui sont d'un ordre de grandeur supérieurs à tout ce qui a été rapporté pour tout autre dispositif décrit dans le domaine.
