A blob of putty that can “feel” being stretched? G-putty mixes graphene flakes into a soft material, creating a conductive network that’s always rearranging itself. Pull, press, or twist the putty and those tiny pathways connect, break, and reconnect. Click to learn how g-putty turns squishy motion into an electrical signal!
Scientists have developed a way to engineer new forms of matter by stacking different types of layers, each only one atom thick, on top of one another.
Graphene is a two-dimensional material made from a single sheet of atoms, with outstanding mechanical, electronic, and thermal properties. It is a promising candidate to enable next-generation technologies in a wide range of fields, including electronics, energy, and medicine. This economical, safe, and simple lab activity allows students to make graphene via chemical vapor deposition in 30–45 minutes in a classroom setting.
