Abstract:
Disposable Clark-type oxygen electrodes were
fabricated using filter paper as the substrate of the electrodes, which also
served to absorb the electrolyte required. The oxygen electrode has a
two-electrode configuration and both the anode and cathode were deposited
directly on filter paper by sputtering a layer of silver. Silicone rubber was
used as the gas-permeable membrane. The whole fabricating procedure dispensed
with the expensive photolithographic process used in silicon- and glass based
oxygen electrodes, decreasing both the cost and time required for fabrication.
The electrodes showed good characteristics for voltammetrically detecting
dissolved oxygen and their dynamic range covered the entire possible range of
dissolved oxygen concentrations. The electrodes had a 90% response time of 12
seconds and a life time of about 2 hours.
