Abstract: We provide an electrochemical sensor in which working microelectrodes are arranged in an array and interconnected in parallel. The working electrodes are arranged so that in use, they are electrochemically coupled to a counter electrode structure through an electrolyte. The sensor also includes a microporous body arranged so that in use, it is situated at a boundary between a gaseous environment and the electrolyte. In another aspect, we provide a method of sensing in which a sample of gas is admitted to a liquid electrolyte maintained by pores of a porous substrate. A voltage is applied to the liquid electrolyte, and an electrical response to the applied voltage is observed, thereby to detect electrochemical evidence of an analyte within the liquid electrolyte.

Abstract: Provided is a gas sensor and methods of monitoring the same. The gas sensor may detect gas restrictions within the gas sensor. The gas sensor may include a test gas diffusion path allowing for monitoring of restrictions within the gas sensor. A pulse of test gas may be electrochemically generated into a void disposed between the membrane and capillary of the gas sensor. The resulting transient signal on the sensing electrode may be analyzed to determine the degree of restriction present in the gas sensor.

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.
