▎ 摘  要

NOVELTY - The system has a processing unit, and a graphene transistor (gSGFET) comprising graphene as a channel material that is contacted by two terminals. A variable voltage source is provided to the drain terminals and graphene transistor source (gSGFET) referred to the gate voltage. A filter is configured to acquire and separate the transistor signal into two frequency bands, high and low frequency bands, where the first and second signals are respectively amplified with a gain value. USE - Graphene transistor system for electrophysiological signal measurements. ADVANTAGE - The good isolation of the passivation layer and the reactivity insignificant graphene can be demonstrated. The size of the electrodes are reduced to achieve a higher spatial resolution causes the intrinsic high pass filtering of ISA due to the increase in impedance of the associated electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for measurements of electrophysiological signals using the graphene transistor system. DESCRIPTION OF DRAWING(S) - The drawing shows a circuit diagram of the graphene transistor.
