Abstract
The present disclosure provides a graphene based dry electrode for electrophysiological readings, in particular for use with EEG, EKG, EMG, and EOG systems and a method for making said electrodes. The electrodes comprising a doped silicon substrate; a silicon carbide film on the substrate; a graphene surface on the silicon carbide film; wherein the graphene surface has undergone a functionalisation and/or intercalation process to increase the amount of oxygen functional groups present, said process being preferably carried out through repeated contact of the graphene surface with an electrolyte solution.
