Graphene can hear your brain whisper

(Graphene Flagship) A newly developed graphene-based implant can record electrical activity in the brain at extremely low frequencies and over large areas, unlocking the wealth of information found below 0.1 Hz. This technology, which will be showcased in the Graphene Pavilion at Mobile World Congress in Barcelona (25-28 February 2019) was developed by Graphene Flagship partners at the Barcelona Microelectronics Institute (IMB-CNM, CSIC), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), and ICFO.
