ABSTRACT:
A biosensor for measuring alcohol concentration includes an insulating substrate and an amperometric device formed on the insulation substrate, having a plurality of conductive lines and connective pads and a plurality of electrodes. An enzyme immobilized layer is formed on one of the plurality of electrodes of the amperometric device and an enzyme paste is printed on the amperometric device. An outer membrane is formed on the substrate having the plurality of electrodes for forming an electrode system and an insulating membrane is formed on the substrate, except on the outer membrane.
