An analyte multi-sensor as disclosed herein can include a substrate and at least three sensing elements disposed on the substrate.  Each sensing element includes two electrodes separated by a distance and a nanowire mat adjacent to and in contact with the electrodes.  The nanowire mats include nanowires which define a percolation network.  The density of the nanowires in the nanowire mat of one sensing element is different than the density of the nanowires in the nanowire mat of either of the other at least two sensing elements.
