<p>The electro-chemical sensor comprises a substrate (1) supporting two current conducting bands (4,5) of width L & L'. The facing edges of these two bands (4a,5a) are isolated from each other by a space of width delta. A covering film (2) comprising a connection window and a measurement window lies over the conduction bands. The film includes two openings (12,13) separated by a portion (14) which defines the useful working surfaces of the electrodes (16,17). The apertures (12,13) have accurately determined dimensions with respect to the median line of the sensor. The two apertures are symmetrical, so that the surfaces of the electrodes are identical.</p> |
