New material derived from keratin can remember and change shape

摘要

Researchers at Harvard John A Paulson School of Engineering and Applied Sciences (SEAS) have explored the shape memory capabilities of our hair to develop a similar material that could be used in textiles.Explaining the shape memory concept, they provide the example of hair 'bouncing back into curls' once it touches water, because its material properties allow it to change shape in response to certain stimuli and return to its original shape in response to others.
