Abstract
The present invention concerns an electrochemical sensor made up of an insulating base having an electrode layer on its surface and a lid of deformable material which comprises a concave area in the central portion thereof, so that when it is mated with the base, the lid and base form a capillary space containing the electrode layer. When the electrode layer is in operative contact with a reaction layer comprising an enzyme which will cause the production of mobile electrons when contacted with a suitable analyte, the concentration of analyte, e.g. glucose in blood, can be measured by measuring the current created by the flow of mobile electrons when contacted with a suitable analyte, the concentration of analyte, e.g. glucose in blood, can be measured by measuring the current created by the flow of mobile electrons.
