Abstract:
1. An electrochemical gas sensor, comprising: an electrode assembly including a first planar substrate having a first surface and a second surface, the second surface having at least one planar electrode formed thereon; a housing having a cap member and a body, the body defining a reservoir which, in use, holds liquid electrolyte for contact with the at least one planar electrode, the body being molded around the electrode assembly such that the body is in contact with both the first and second surfaces of the first planar substrate, the body having electrically conductive polymer portions and nonconductive portions being co-moulded with each other, wherein each of the electrically conductive polymer portions is accessible from an exterior of the housing, wherein each of the electrically conductive polymer portions is isolated from the other electrically conductive polymer portions by the nonconductive portions, wherein the cap member is sealed to a portion of the body facing the first surface of the first planar substrate; wherein a portion of the at least one planar electrode is sealed to the electrically conductive polymer portions of the housing and where each of the electrically conductive polymer portions extends from an interior of the housing that defines the reservoir to the exterior of the housing.
