Shape memory alloy smart material
Did you know?
In metallurgy, a shape-memory alloy (SMA) is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. It may also be called memory metal, memory alloy, smart metal, smart alloy, or muscle wire. Parts made of shape-memory alloys can be lightweight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based systems. They can also be used to make hermetic … WebbShape memory alloys (SMAs) are materials that can be deformed at one temperature but when heated or cooled, return to their original shape, i.e. the alloy appears to have a memory. Strains of up to about 10% can be fully recovered. Alloys that exhibit this effect only when heated are said to have a "one-way shape memory".
Webb[13, 14] In the case of metals, shape memory alloys (SMAs) are of particular interest due to the large strains these materials can withstand. They have been investigated as relatively large-format auxetic TiNi antennas [ 15 ] 4D printed ballistic panels with TiNi, [ 16 ] 4D printed Fe-Mn-Si based SMAs, [ 17 ] and auxetic unit cells made of superelastic … Webb8 apr. 2024 · Smart responsive materials can react to external stimuli via a reversible mechanism and can be directly combined with a triboelectric nanogenerator (TENG) to deliver various intelligent applications, such as sensors, actuators, robots, artificial muscles, and controlled drug delivery.
