Listening to the Brain with a Graphene Sensor
“Graphene Flagship,” a consortium of 150 research groups, headquartered Chalmers University of Technology (Gothenburg, Sweden), has developed an implantable graphene sensor that can detect very low frequency impulses in the brain. “This new technology moves away from electrodes and uses an innovative transistor-based architecture that amplifies the brain’s signals in situ before transmitting them to a receiver. The use of graphene to build this new architecture means the resulting implant can support many more recording sites than a standard electrode array. It is slim and flexible enough to be used over large areas of the cortex without being rejected or interfering with normal brain function. The result is an unprecedented mapping of the low frequency brain activity known to carry crucial information about different events, such as the onset and progression of epileptic seizures and strokes.” MORE
