Abstract
The present invention concerns a membrane electrode for measuring glucose concentration in liquids, comprising: a base membrane with at least one noble metal electrode which is arranged on one side of the base membrane; a proton-selective ion membrane arranged on the base membrane and the noble metal electrode; and a double membrane which is arranged on the ion membrane and in which glucose oxidase is contained in a suitable medium, and also an electronic circuit for operation of the membrane electrode comprising: a stabilised polarisation voltage source; two high-impedance amplifiers; a parallel resistor; an element for processing and storage of the measured parameter; and an output means.
