Silly putty makes seriously state-of-the-art sensors




Silly putty is more than just child’s play, according to a new paper – it's a key ingredient in a motion sensor precise enough to detect a spider’s tiny footprints.
Conor Boland, a nanophysicist at Trinity College Dublin in Ireland, and colleagues combined the popular children’s play-goo with graphene: single layers of pure carbon atoms bonded in a honeycomb formation. The result, dubbed “G-Putty”, was unveiled in Science.
