Printed graphene oxide makes for interesting electronic devices

Researchers at the Barcelona Institute of Science and Technology have managed to print graphene oxide onto different materials, including paper, and use it as a touch sensitive electronic device. They transferred graphene oxide coated on a wax printed membrane to paper, an adhesive film and even a t-shirt by simply using pressure and water, and also printed graphene oxide onto plastic and, as the oxide conducts electricity, used it as a touch sensitive LED switch.
