New hydrogel material works like human muscle - Science and technology news articles

A new material made from a double-network of hydrogels has the ability to increase its strength in response to mechanical stress, similar to the human muscles. This ability allows the material to repair the damage induced by tensile forces.

The material contains two intertwined networks of polymer strands, with one network rigid and the other one flexible. The rigid component breaks down when mechanical stress is applied, but this triggers a local polymerization process that creates new bounds within the material, making it strong again. The soft component helps maintain its shape and the gel appearance.

This process is pretty similar to what happens inside muscles during intense exercise. The new self-growing fatigue-free material could be used for various applications, from soft robots to medicine.
