Shape Memory Alloys
/ʃeɪp ˈmɛməri ˈælɔɪz/noun
ELI5 Mode🧒
Shape memory alloys are innovative metallic materials that can revert to their original shape after being deformed, triggered by temperature changes through a process called the shape memory effect. This property makes them essential in modern engineering for creating adaptive devices, such as in robotics or medical implants, where they offer reliability and efficiency in dynamic environments.
