Created fiber, which can be a "skin" for robots
Source:
Unfortunately, scientists have not yet invented the perfect material, which possesses all the properties at once — while it sounds like science fiction. However, they are working to create a versatile fiber that can be used in the maximum number of devices ranging from cars and ending with robotics. A team of researchers from the University of North Carolina approached it, providing a wire, having strength and elasticity. Maybe he'll make a great material to protect the innards of robots.
Created by researchers at the fiber has a metal core of gallium and wrapped the elastic polymer shell of styrene, ethylene and butylene. Initially, the wire has a metallic strength, but shattered the heart to pieces, it can be stretched to seven times its original length. Gallium, which is inside, has a melting temperature of only 30 degrees, so after returning the fiber to its original state can easily recover and regain strength.
According to study author Michael wild, to stretch the polymer shell does not need more power. This means that woven out of a fiber material can cover the moving parts of robots. Being stationary, they are under full protection, and when they move freely to stretch and harden again when you stop. Due to the content of gallium, the fiber can withstand a weight of 15 000 times its own weight.
Development of new materials is ongoing. A team of scientists from the University of California in Los Angeles recently managed to create , which in the future will be used to protect missiles and vehicles from high temperatures.
