When you want to move an object from one place to another, you usually grab it with your hands or a robotic arm. But what if you want to move something you cannot touch without damaging or disrupting ...

A team of Georgia Tech and Ohio State University researchers has developed a soft polymer material, called magnetic shape memory polymer, that uses magnetic fields to transform into a variety of ...

Since magnetic-field-induced strain was reported for NiMnGa (refs 1, 5), many other ferromagnetic shape-memory alloys, such as FePd (refs 2, 6, 7), FePt (ref. 8), NiCoGa (refs 9, 10), NiCoAl (refs ...

The magnetic shape memory effect can be used for designing actuators where the element elongates based on the presence of a magnetic field. The elongation can be reversed fully either by the ...

What are shape memory polymers? Shape memory polymers were first conceived back in the 1940s when L. B. Vernon and his colleagues discovered the shape memory properties of polymers, reported in a 1941 ...
