Utilizing graphene wrapped silver nanoparticles suspended in a PVA/PVDF/PVP gel electrolyte I think I can make entirely reusable electromyogram sensor pads.
Using a small percentage of DMSO (20%) and NaCl or sodium bicarbonate ionic conductivity can be vastly improved by bypassing the skin completely. DMSO is a polar aprotic solvent that passes through skin without any resistance.
The problems are in getting the ionic conductivity and electrical conductivity tuned to provide the least amount of resistance possible. This is easier said than done in a solid gel electrolyte especially considering it must be skin compatible.
The graphene and silver are below 2 ohms when used in conjunction which should allow a proper signal to reach the current collector backer.
I will use my 3d printer to print molds and pour the electrodes in for curing and then hopefully pop them out just as easily as they went in.
