Title
(EN) ACTUATOR DEVICE USING SHAPE MEMORY ALLOY ELEMENT
(FR) DISPOSITIF ACTIONNEUR UTILISANT UN ÉLÉMENT EN ALLIAGE À MÉMOIRE DE FORME
Abstract
(EN)
An actuator device (100) comprising a shape memory alloy, SMA, element (101) configured to transition between an expanded state (201) and a contracted state (202); an actuation member (103) coupled to the SMA element (101) to displace between a first position (251) and a second position (252) when the SMA element (101) transitions between the expanded state (201) and the contracted state (202); an elastic element (105) configured to bias the SMA element (101) towards the expanded state (201); and a locking element (104) configured to selectively lock the actuation member (103) in the first position (251) when the SMA element (101) is in the expanded state (201).
(FR)
Dispositif actionneur (100) comprenant un élément en alliage à mémoire de forme (SMA) (101) configuré pour passer d'un état déployé (201) à un état contracté (202); un élément d'actionnement (103) couplé à l'élément SMA (101) pour se déplacer entre une première position (251) et une seconde position (252) lorsque l'élément SMA (101) passe entre l'état déployé (201) et l'état contracté (202); un élément élastique (105) configuré pour solliciter l'élément SMA (101) vers l'état déployé (201); et un élément de verrouillage (104) configuré pour verrouiller sélectivement l'élément d'actionnement (103) dans la première position (251) lorsque l'élément SMA (101) est dans l'état déployé (201).
