A good tire means a lot when the nearest roadside assistance is 34 million miles (55 million kilometers) away. For future rovers that will explore the surface of Mars, NASA scientists have created a ...

Virginia Tech advances additive friction stir deposition - creating a strong, defect-free material that can be 3D printed in bulk.

Shape-memory metals, which can revert from one shape to a different one simply by being warmed or otherwise triggered, have been useful in a variety of applications, as actuators that can control the ...

NASA is working on shape memory alloy tires for future missions to Mars, figuring out ways to give rovers and more an airless, shapeshifting wheel. While NASA's Perseverance rover is headed off to ...

Engineers at Saarland University have taken a leaf out of nature's book by equipping an artificial hand with muscles made from shape-memory wire. The new technology enables the fabrication of flexible ...

Known to many as muscle wire or memory metal, shape memory alloys are materials that can be bent or deformed, and then return to their original shape when heat is applied. While people are most ...
