Thubber is a unique rubber material with metal properties

Researchers at Carnegie Mellon University have developed a rubber material that stretches six times its original length and has high thermal conductivity. Perhaps, in the near future, he will help in the creation of soft, elastic robots and flexible electronics.

The main component of the material, called "thubber" - non-toxic liquid metal droplets integrated into the rubber, which easily stretch with it. When stretched, the droplets elongate, providing heat flow over the entire surface of the material. Moreover, despite the presence of metal, the material is electrically insulating.

Scientists have demonstrated several examples of the use of thubber, in particular, as a base for LED lighting on the runner's leg and for the flexible tail of a robot fish. In the future, a unique elastic material can become the basis for artificial muscles.
