Researchers from Rice University have created a way for edible RFID tags to be printed on food, cloth, cardboard and paper, introducing what it calls a "new class of edible electronics."
Previously, Rice University unveiled laser-induced graphene (LIG), finding that anything with the right carbon content can be turned into graphene—a thin layer of pure carbon. As chemist James Tour notes: "This is not ink, this is taking the material itself and converting it into graphene."
As part of its experiments, Rice University created LIG patterns on everything from potatoes and coconut shells to cork and toast. In terms of this technology's potential applications, the possibilities are immense when it comes to communicating more information about a product, including its origins or its freshness, without the need for extraneous materials.
