Shape memory alloys
Shape memory alloys (SMAs) are special metals that can 'remember' their original shape. When these alloys are deformed at a certain temperature, they can return to their original form when heated beyond a specific threshold. This unique property is due to changes in their crystalline structure. SMAs are used in various applications, like medical devices, such as stents, and in robotics, where they can create movement with heat. Their ability to adapt and return to a predefined shape offers innovative solutions in engineering and design.

Shape Memory Alloys (SMAs) are special materials that can "remember" their original shape when heated. When these metals are deformed at lower temperatures, they can return to their original shape upon heating. This happens due to a unique arrangement of atoms that shifts between two structural forms: one stable at lower temperatures and another at higher temperatures. SMAs are used in various applications, including medical devices, actuators, and robotics, because they can respond dynamically to changes in temperature, providing smart solutions for movement and functionality.

Shape memory alloys (SMAs) are special types of metals that can "remember" their original shape. When they are deformed, they can return to their original form upon heating. This unique property is due to a phase change in the metal's structure. For example, when an SMA is cooled, it may bend or twist, but when heated, it straightens out again. SMAs are used in various applications, such as medical devices, robotics, and actuators, because they can respond to temperature changes, providing movement or force without the need for traditional motors or mechanisms.
