Abstract
Apparatus and associated methods relate to a one-piece structure for a solid electrolyte chemical sensor (SECS) having a first surface defining a cavity (210, 305, 415) designed to receive a substrate (215, 350, 410) that retains a solid electrolyte (365, 440), an internal water impermeable coating (425) on at least a portion of the first surface, a second surface that is substantially coplanar with an adjacent peripheral edge of a top surface of the substrate (215, 350, 410) when the substrate (215, 350, 410) is received in the cavity (210, 305, 415), and a plurality of electrical contacts (335, 340, 345, 450a-450b) disposed on the second surface adapted to electrically couple with the electrodes (435a-435c) on the substrate (215, 350, 410) when the substrate (215, 350, 410) is received in the cavity (210, 305, 415) and electrical paths are provided between respective electrical contacts (335, 340, 345, 450a-450b) and electrodes (435a-435c).
