✦ Synopsis

A Clark-type oxygen electrode with three electrodes has been fabricated using semiconductor techniques and its characteristics compared with those of double oxygen electrodes with a similar structure. The 90% response time is 40 s, the residual current at zero oxygen concentration is less than 7%, and the linearity is good. The oxygen electrode can be used for 25 h at -0.6 V. These characteristics are affected by electrochemical crosstalk between the electrodes and are improved by varying the electrode configuration.

A miniature Clark-type oxygen electrode was fabricated by anisotropically etching silicon. A two-gold-electrode configuration was used and a double-layered gas-permeable membrane was formed directly on the electrolyte, poly(vinyl-4-ethylpyridinium bromide) in the sensitive area.

A procedure for calibrating a Clark-type oxygen electrode is described. This method is based on the oxidation of 4-tert-butylcatechol (TBC) by O2 catalyzed by tyrosinase, to yield 4-tert-butyl-o-benzoquinone (TBCQ). This reaction consumes known amounts of oxygen in accordance with the stoichiometry:
