ABSTRACT:
Toys of any shape which recover their original shapes after deformation when they are heated by electrical or thermal stimulus are introduced. The deformation and shape recovery action can be repeated. The form regaining action is achieved by a special characteristics of the shape memory alloys, for example, nitinol, which change their phase and thereby change their shapes when their temperature is raised beyond their transition temperature. Toys are covered by a soft plastic to enhance the look of them.
