Graphene sensors read low-frequency neural waves associated with distinct brain states
A biocompatible implant based on graphene safely measures and predicts brain states.
Graphene Flagship scientists have developed a sensor based on CVD graphene that detects brain signals in a wide frequency band, from extremely low frequencies to high frequency oscillations. The sensor is biocompatible and could be used to measure and predict brain states. Furthermore, the graphene sensors could be used in chronic implants due to their high stability in the brain.
The study was conducted by scientists at Graphene Flagship partners the Catalan Institute of Nanoscience and Nanotechnology (ICN2), the Microelectronics Institute of Barcelona (CSIC), CIBER-BBN and ICREA, Spain, Ludwig-Maximilians University, Germany, and the University of Manchester, UK, in collaboration with Graphene Flagship partner Multi Channel Systems GmbH, Germany.
The consortium showed that graphene-based sensors grant access to an elusive low-frequency region of brain activity.
