Abstract
An ink mixture is manufactured by mixing carbon, graphite, and solvents in a mixing system which may include a Cowles disperser. The conductive portions (e.g. carbon, graphite) are evenly and universally dispersed, because an even dispersal means the conductivity of the resulting conductive strip (electrode) will be even, consistent, and reliable. The various embodiments of the ink mixture comprise a blend of different conductive pigments, including but not limited to carbon black and graphite. These embodiments must be grinded until below 6.5 Microns in particle size.
