What is the memory wire?

Memory wire is a type of shape memory alloy, typically made from nickel and titanium, which can "remember" a predetermined shape. When heated above a specific temperature, it returns to this original shape after being deformed. This unique property is utilized in various applications, including medical devices, robotics, and jewelry, where it can provide flexibility and resilience. Its ability to revert to a set form makes it particularly valuable in situations requiring precise movement or tension.
