A new material that once deformed will automatically return to its original shape when heated has been developed by researchers in the US. While this is not the first such “shape-memory metal”, 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 ...

A rover on the Moon has metal wheels that can flex around rocky obstacles, then reshape back to their original form. On Earth, surgeons install tiny mesh tubes that can dilate a heart patient’s blood ...

You’ve likely heard of Nitinol wire before, but we suspect the common base knowledge doesn’t go much beyond repeating that it’s a shape-memory alloy. [Bill Hammack], the Engineer Guy, takes us on a ...

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 ...

Another Kickstarter, another opportunity for people to get mad at delayed and poorly functioning (if delivered at all) gadgets. This project aims to make airless tires for bikes and scooters using ...

Inspired by the Portulaca oleracea seedcoat, metamaterials fabricated by laser powder bed fusion realized tunable in-plane mechanical properties, large deformation recovery capability and functional ...
