#IMBCNMTalks: Neural interfaces based on flexible graphene transistors
By Anton Guimèra (GAB researcher).
Thanks to their unique set of properties, graphene enables the implementation of the so-called graphene based solution-gated field-effect transistor (gSGFET) as novel transducer for neural signals. gSGFETs are able to overcome the limitations of passive electrodes in DC coupled operation, enabling the recording of infra-slow activity (ISA). The use of a transistor as a transducer also enables the implementation of multiplexing strategies by addressing arrays arranged in rows and columns. This fact allows to reduce the connectivity and scale up in number recording sites.
