Abstract
An electrode comprises a non-conductive substrate and a conductive layer comprising, in a bonded matrix, graphite particles coated with a noble metal, and carbon particles, wherein the graphite particles are up to 20 .mu.m is size and have a surface area of 1-50 m.sup.2 /g. This electrode is capable of measuring low levels of analyte, e.g. glucose in sweat when convined with a layer containing glucose oxidase.
