PROBLEM TO BE SOLVED: To provide a shape recovery device having bidirectional shape recovery actions and good responsibility to temperature by laminating a shape memory composite composed of a shape memory allay having a specified shape recovery temperature and generation force and shape memory polymer having memory of a shape in different direction from the recovery action of the alloy, a Peltier element, a radiator in sequence. SOLUTION: In a shape recovery device, a shape memory composite 3, a Peltier element 4, and a radiator 5 are laminated in sequence. The shape memory composite 3 is composed of a shape memory alloy 1 having memory of a shape recovery action and a shape memory polymer 2 having memory of a shape recovery action in different direction from the recovery action of the alloy 1. The shape recovery temperature (martensite reverse modification temperature Af) of the alloy 1 is made higher than the shape recovery temperature (glass transition temperature Tg) of the polymer 2. Besides, a temperature at which (recovery stress×cross section) or the generation force of the alloy 1 is equal to (recovery stress×cross section) of the polymer 2 is set up to come between Af and the martensite modification temperature (Mf) of the alloy 1. |
