1. A process for manufacturing an electrochemical sensor, comprising:
moving a metal wire from a wire feed unit to a wire pick-up unit, the moving wire passing at least one printer Pcond which is located in between the wire feed and wire pick-up units;
printing an ink which comprises electrically conductive particles by the printer Pcond onto discrete arrays of an electrically insulating polymer coating which is present on the metal wire;
wherein the metal wire comprises a working electrode of the electrochemical sensor; and
cutting the metal wire into individual pieces at a wire cutting unit that is located downstream of the wire pick-up unit;
wherein the discrete arrays have a size of 100 μm2 to 10000 μm2.
