Material Gets Stronger When Stretched

Feb-07-19 An innovative regenerative material mimics muscles to grow stronger as it is used.

Created by a team at Hokkaido University, the material is made up of a double-network hydrogel, which features both a rigid and a stretchable polymer. When the polymer is stressed and then submerged in a bath of monomers, the broken, rigid material bonds readily with the floating monomers and forms a stronger polymer chain.

The team believes the regenerative material could have applications in exosuits that grow stronger over time for patients with spinal injuries.
