Graphene is both transparent and opaque to radiation

06. A microchip that filters out unwanted radiation with the help of graphene has been developed by scientists from the EPFL and tested by researchers of the University of Geneva (UNIGE). The invention could be used in future devices to transmit wireless data ten times faster. EPFL and UNIGE scientists have developed a microchip using graphene that could help wireless tele share data at a rate that is ten times faster than currently possible. The results are published today in Nature. "Our graphene based microchip is an essential building block for faster wireless tele in frequency bands that current mobile devices cannot access," says EPFL scientist Michele Tamagnone. Graphene acts like polarized sunglasses Their microchip works by protecting sources of wireless data - which are essentially sources of invisible radiation - from unwanted radiation, ensuring that the data remain intact by reducing source corruption.
