Abstract
A method for producing a pH half-cell by means of which, in combination with a reference electrode and an evaluation electronics unit, a pH value of a medium can be determined, comprises the following steps: applying a first structure and a second structure to a substrate, wherein the first structure is applied by means of a thin-film method and forms a resistance element having a temperature-dependent resistance value, and wherein the second structure can be employed to derive a pH-dependent potential; applying a structured passivation glass layer, wherein the passivation glass layer substantially covers the first structure and leaves the second structure substantially uncovered; applying a mixed-conducting glass, wherein the mixed-conducting glass is substantially applied to the region that was left uncovered by the passivation glass layer; and applying a pH-sensitive glass, wherein the pH-sensitive glass is applied to the mixed-conducting glass.
