To maintain the shape-memory effect, the researchers used two different oxides, barium titanate, and cobalt ferrite, which they implemented in thin layers onto a magnesium oxide substrate. The lattice ...

The shape memory effect of PEEK was investigated during full-bending deformation (180) at an actuation current of 0.24 A. After 15 seconds of powering on, the temperature hit 170 degrees celsius, and ...

Shape memory alloys can be deformed into different shapes when cold, but will revert back to their original shape when heated (as if "remembering" their default state, like memory foam).

On the material side: Nitinol and other shape-memory alloys generally require extensive mechanical processing—called “cold work”—to achieve the shape-memory effect.
