Abstract:
1. An electrochemical sensor for measuring concentration of an analyte in a sample fluid, comprising a co-planar electrode system and a sample receiving area, the electrode system comprising a plurality of electrodes each having a distal end at least partially exposed within the sample receiving area and a proximal end comprising a contact pad, each distal end being connected to a corresponding contact pad by a trace lead extending therebetween, each contact pad being configured for electrical connection to a meter configured for use with the electrochemical sensor; wherein first and second electrodes of the plurality of electrodes have respective contact pads laterally spaced apart with a space between them, a third electrode of the plurality of electrodes being located substantially entirely between the first and second electrodes, the contact pad of the third electrode being located entirely between the respective trace leads of the first and second electrodes, the third electrode further comprising a terminal extension extending from the contact pad thereof into the space between the contact pads of the first and second electrodes.
