Graphene Ink Moves Bendy Gadgets Closer to Reality

A digital screen that you can fold up like paper, solar cells embedded in house paint and a battery printed on the bottom of your phone — all this may soon be possible thanks to the so-called graphene ink, printed circuits made from graphene — a one-atom-thick layer of carbon that is the strongest, thinnest and most conductive material discovered yet.

Conductive inks — printed circuits — are already widely used to make touch screens, RFID tags (radio-activated ID chips) and small antennas in mobile phones. However, today’s conductive inks are usually metal-based, using materials like silver or copper powder.
