Biosensor and related wound dressing system

A biosensor for detecting a biomarker in a bodily fluid, secretion or exudation, comprising:

• a first electrode, wherein said first electrode is electrically conductive and comprises a first exposed electrically conductive outer surface extending longitudinally along said first electrode;
• a second electrode, wherein said second electrode is electrically conductive and comprises a second exposed electrically conductive outer surface extending longitudinally along the second electrode;
• a first insulating partial surface provided between said first electrode and said second electrode having a first side adhered to a first portion of less than all of said first exposed electrically conductive outer surface;
• a second insulating partial surface provided between said first electrode and said second electrode having a first side adhered to a second portion of less than all of said second exposed electrically conductive outer surface;
• a mechanical electrode stabilizer formed from a non-conductive material or a semi-conductive material and positioned in a gap between said first insulating partial surface and said second insulating partial surface, wherein said mechanical electrode stabilizer is configured to keep the first electrode longitudinally parallel with the second electrode, wherein said mechanical electrode stabilizer is adhered to a second side of said first insulating partial surface opposite said first side of the first insulating partial surface, and is adhered to a second side of said second insulating partial surface opposite said first side of the second insulating partial surface so as to maintain the first electrode and the second electrode in a substantially parallel longitudinal orientation, wherein the mechanical electrode stabilizer forms an integral part of a wound dressing substrate;
• an electrode coating, wherein said electrode coating comprises a natural or synthetic substrate of said biomarker and an electrical booster, said electrical booster configured to decrease the impedance between said first electrode and said second electrode when mechanically released from an immobilized form in said electrode coating upon induced chemical and related mechanical degradation thereof by said biomarker;
• at least one of a remaining portion of the first exposed electrically conductive outer surface or a remaining portion of the second exposed electrically conductive surface being fully covered by said electrode coating;
• said biomarker being an enzyme configured to catalyze a chemical reaction in which a singularity or plurality of constituents of said electrode coating are chemically altered by the breaking of covalent chemical bond when in contact with said biomarker;
• and
• said biosensor configured to exist in at least one state of a group of states comprising a high impedance state, in which said electrode coating is chemically unaltered by said biomarker, and a low impedance state, in which said electrode coating is chemically altered by said biomarker.
