(57) [Abstract] [Purpose] By combining a shape memory material and a ferromagnetic material, it reacts to an externally applied electromagnetic field, is movable, and self-heats due to the electromagnetic induction eddy current effect. By this, the shape memory element itself forms a composite functional material element that can be self-deformed to the previous memory shape state. [Structure] Ferromagnetic ferrite fine iron wire (1) is replaced with Ti-Ni Wound and bonded on the surface of the shape memory alloy (2) to form a composite functional material element capable of self-heating and self-deformation due to the effect of electromagnetic induction eddy current generated in an external electromagnetic field. |
