Shape memory polymers (SMPs) are smart materials that can be deformed into a temporary shape and then return to their original, "permanent" shape when triggered by an external stimulus, most commonly heat, but also light, moisture, electric current, or magnetic fields. Unlike shape memory alloys such as Nitinol, which rely on a metallic crystal-phase transformation, SMPs achieve this effect through their polymer network structure, which makes them lighter, cheaper to process, and capable of much …
