Abstract:
Clark was the first to couple an electrochemical sensor with gas permeablemembrane e. g. polyethylene membrane for blood analysis. This type of mem-brane-covered sensors has found wide applications. The oxygen permeability of the membrane and geometry of the cathode are generally considered to be the main factors in controlling the characteristics of Clark-type sensors. Sawyer et al.
