Introduced to United States in 1984 after its original introduction in Japan.
Combination of Polymeric materials with the capability to temporarily deform then restore to their original shape through thermal stimuli such as temperature change.
Exhibit long covalent cross linked bonds.
Tested to potentially deform up to 200% of their original state and still restore their original shape.
Light weight
Potentially biodegradable for surgical procedures
Cheaper to manufacture than Shape memory Alloys.
Applications
