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.
“Our graphene based microchip is an essential building block for faster wireless telecommunications in frequency bands that current mobile devices cannot access,” says EPFL scientist Michele Tamagnone. Their microchip works by protecting sources of wireless data from unwanted radiation, ensuring that the data remain intact by reducing source corruption.
They discovered that graphene can filter out radiation in much the same way as polarized glasses. The vibration of radiation has an orientation...
