Abstract
In various embodiments, methods and systems, of an ionic varistor system is provided. The ionic varistor system includes an electrolyte-membrane assembly having a liquid electrolyte that is enclosed in a solid electrolyte membrane. The ionic varistor system further includes conductive contacts operably coupled to the electrolyte-membrane assembly. The electrolytic-membrane assembly is operably coupled to an electrical potential surface. As the ionic concentration in the electrical potential surface is increased or decreased, some ions diffuse through the solid electrolyte membrane, causing the ions to mix with the liquid electrolyte to achieve an electrostatic equilibrium state that is thermally and mechanically stable. The liquid electrolyte and the diffused ions create an encapsulated ion channel in the electrolyte-membrane assembly. The electrical conductivity of the encapsulated ion channel increases as the ion concentration increases such that the complete electrolyte-membrane assembly produces electrical resistance. The ion concentration is measured as indicator of electrical potential of the electrical potential surface.
