Get Ready for Ultra-Thin Invisible Body Armor

Graphene, which is as common as the flakes from your pencil when you write, is turning out to be the wonder material of the new millennium. A few years ago, researchers discovered its electrical properties, which make one-micron sheets of the stuff ideal for tiny computerized devices. Now a new study reveals that graphene may also be one of the strongest materials known to humans. It has a breaking strength of 55 newtons per meter. That means if you had a sheet of graphene that was the thickness of typical plastic wrap, it could support the weight of a 2000 kg car before breaking. Just to make things even more mega, graphene is also transparent. Ultra-thin, invisible body armor, here we come! [New Scientist] Image via Coderforfood.
