Title (EN) SHAPE MEMORY ALLOY ACTUATORS AND METHODS THEREOF
(FR) ACTIONNEURS EN ALLIAGE À MÉMOIRE DE FORME ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) SMA actuators and related methods are described. One embodiment of an actuator includes a base; a plurality of buckle arms; and at least a first shape memory alloy wire coupled with a pair of buckle arms of the plurality of buckle arms. Another embodiment of an actuator includes a base and at least one bimorph actuator including a shape memory alloy material. The bimorph actuator attached to the base.
(FR) L'invention concerne des actionneurs en SMA et des procédés associés. Un mode de réalisation d'un actionneur comprend une base ; une pluralité de bras de boucle ; et au moins un premier fil en alliage à mémoire de forme accouplé à une paire de bras de boucle de la pluralité de bras de boucle. Un autre mode de réalisation d'un actionneur comprend une base et au moins un actionneur bimorphe comprenant un matériau en alliage à mémoire de forme. L'actionneur bimorphe est fixé à la base.
