A Tablecloth to Charge Your Laptop

moscowde writes "Research scientists at the University of Tokyo have come up with a unique sheet-like material that can transmit electrical energy over a large area to nearby devices without the need for direct contact, so it can be made into a tablecloth or wallpaper and your appliance can be anywhere on a surface to get charged. The system uses organic molecules as transistors, microelectromechanical switches, and miniature copper coils to transmit energy using electromagnetic induction."
