Here is a thermally conductive rubber that can be used to develop advanced wearables and robot muscles. Thubber not only has metal-like thermal conductivity but also elasticity similar to a soft tissue. It can stretch over six times its initial length.

The key ingredient in “thubber” is a suspension of non-toxic, liquid metal microdroplets. The liquid state allows the metal to deform with the surrounding rubber at room temperature. When the rubber is pre-stretched, the droplets form elongated pathways that are efficient for heat travel. Despite the amount of metal, the material is also electrically insulating.

explained researchers at Carnegie Mellon University. The robotic fish in the above video has a thubber tail to switch without using motors or gears. Promising, don’t you think?
