Abstract

An actuator comprises an elongated shape-memory element wound around a first element and having one first end connected to the first element and one second end connected to a second element. Heating means are provided for heating the shape-memory element in order to obtain a displacement of one of the ends thereof. The elongated shape-memory element is guided so that it can slide within a closed channel made of a material having a low coefficient of friction, for example defined by a sheath.
