Supercharged silly putty can detect spider footsteps

Copyright: Science

The future of blood pressure readings could come in the form of supercharged silly putty—or as the scientists who created it call it, G-putty. So what turns silly putty into G-putty? Graphene. The thinnest, strongest material known to exist, graphene is also extremely flexible. It’s made of a single layer of bonded carbon atoms, and conducts electricity remarkably efficiently. Researchers assembled tiny sheets of graphene only a nanometer thick and inserted them into a stretchy silicone polymer (same thing as silly putty). These graphene nanosheets created a microscopic network of electrical conductors within the putty. | Read more ...
