Abstract: An electrical isolation process, including: receiving a substrate including a layer of carbon-rich material on silicon; and selectively removing regions of the substrate to form mutually spaced islands of the carbon-rich material on the silicon; wherein the layer of carbon-rich material on silicon includes the layer of carbon-rich material on an electrically conductive layer of silicon on an electrically insulating material, and the step of selectively removing regions of the substrate includes removing the carbon-rich material and at least a portion of the electrically conductive layer of silicon from those regions to provide electrical isolation between the islands of carbon-rich material on silicon.

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.

Abstract: A process for producing a solid-state supercapacitor, including the steps of: forming at least one pair of mutually spaced electrodes, each said electrode including a graphene surface layer; and introducing a gel electrolyte between the mutually spaced electrodes and onto the graphene surface layer of each electrode to form a double layer supercapacitor, wherein the gel electrolyte is water-based and does not include a redox agent; and applying a voltage across each pair of electrodes to generate an electric field strong enough to decompose water between the mutually spaced electrodes by hydrolysis and functionalise a surface of the electrodes to substantially increase capacitance of the supercapacitor in the absence of a redox agent, the increased capacitance arising from at least one of electrical double layer capacitance of the electrodes and redox reaction capacitance.
