Xavier Illa, Anton Guimrea y Eduard Masvidal, researchers of the CIBER-BBN group GAB Lab at IMB-CNM led by Rosa Villa, are coauthors of a study recently published in “Nature Communication”, in which it is demonstrated that graphene-based active sensor arrays are a mature technology for large-scale application in wide frequency band neural sensing interfaces. NANBIOSIS U8 Micro– Nano Technology Unit has been used in the development of the research.
This research has been carruied out within the framework of the European Project “Graphene Flagship. The 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.
