Accessories like wired earphones have an annoying tendency to cling to all sorts of things and be damaged as a result. A new material could definitively bury this concern by offering almost magical properties. Developed by scientists at the University of the state of North Carolina, as the material is a conductor wire can remain intact by stretching up to eight times its original length. The researchers achieved this by completing an ultra elastic polymer tube with a liquid metal alloy composed of gallium and indium. After trying to incorporate the metal directly into the polymer, the researchers found it was impossible to get maximum elasticity. The solution is based on a flexible component using a conductive component container liquid.
These cables could become useful not only for headphones or phone chargers, but could also see a new industry developing around flexible electronics. However, before the device is invited in our gadgets, scientists must find a way to minimize leakage of the metal when the polymer becomes damaged. Another significant point to take into consideration: indium alloy is used in very small quantities on Earth, and it is widely used in the design of LCD, its price is constantly increasing.
