Title (EN) ACTUATION DEVICE
(FR) DISPOSITIF D'ACTIONNEMENT
Abstract:
(EN) An actuation device comprises at least one electroactive polymer (EAP) layer (52) attached to a carrier (50) and a mechanical structure (56, 58) which defines at least two stable states. The EAP layer is adapted, when driven, to interact with the mechanical structure to switch between the at least two stable states, wherein the mechanical structure retains the electroactive polymer layer in the selected stable state in a non-driven state. In this way, two or more stable states for the device are defined, which can be retained when the EAP is no longer driven.
(FR) Dispositif comprenant une couche de polymère électroactif (EAP) (52) liée à un support (50) et une structure mécanique (56, 58) qui définit au moins deux états stables. La couche de polymère électroactif est conçue, lorsqu'elle est entraînée pour entrer en interaction avec la structure mécanique, pour alterner entre les deux, ou plus, états stables, la structure mécanique maintenant la couche de polymère électroactif dans l'état stable sélectionné dans un état non entraîné. De cette manière, deux, ou plus, états stables pour le dispositif sont définis, lesquels peuvent être maintenus lorsque l'EAP n'est plus entraîné.
