Ever got a dent in your car or other metallic surfaces? If they were made from this stuff, you could fix the dent with a simple hair blower!

How shape memory alloys moves when heated

“Smart materials” such as memory metals are really fascinating, and their full potential is far from known. In this video, Associate Professor of Mechanical Engineering & Materials Science at Yale Dr. Ainissa Ramirez shows us how memory metals change phase and shapes with heat, and why this is so useful for robotics such as the Mars Rover and even in medicine. A must watch for anyone interested in making robots or health related inventions.

This is one of many interesting videos in a series called “Material Marvels” that you can watch on Yale University’s YouTube channel.
