Abstract
(EN) The present invention relates to a thread-like variable stiffness device (10) comprising an elongate shaft (20), said shaft comprising a polymeric material, and a heat conducting device configured to exchange heat with the polymeric material to cause a phase transition of the polymeric material conferring a variable stiffness to the thread-like device (10), characterized in that the polymeric material is a thermoset shape memory material.
(FR) La présente invention concerne un dispositif à rigidité variable de type fil (10) comprenant un arbre allongé (20), ledit arbre comprenant un matériau polymère, et un dispositif thermoconducteur conçu pour échanger de la chaleur avec le matériau polymère pour provoquer une transition de phase du matériau polymère conférant une rigidité variable au dispositif de type fil (10), caractérisé en ce que le matériau polymère est un matériau à mémoire de forme thermodurcissable.
