Measurement of tissue viability

An apparatus for mapping regions of damage around a wound, said apparatus comprising:

• a plurality of electrodes embedded on a substrate configured to be placed over an area of tissue that includes the wound, wherein combinations of said plurality of electrodes are capable of forming a plurality of virtual capacitive sensors, each of said virtual capacitive sensors comprising more than two electrodes of said plurality of electrodes and configured to measure a capacitance of a region of tissue proximate to said respective virtual capacitive sensor,
• a plurality of visual indicators embedded on said substrate, wherein each visual indicator of said plurality of visual indicators is disposed between at least two electrodes, wherein each of said plurality of visual indicators is a light-emitting diode (LED) comprising a plurality of modes of display based on said capacitance measured by said virtual capacitive sensors disposed on each side of said respective visual indicator,
• a drive circuit electronically coupled to said plurality of electrodes and plurality of visual indicators,
• a processor electronically coupled to said drive circuit, and
• a non-transitory computer-readable medium electronically coupled to said processor and comprising instructions stored thereon that, when executed on said processor, perform the steps of:
• receiving information regarding said measured capacitance from a subset of said plurality of virtual capacitive sensors via said drive circuit,
• determining a boundary between viable and non-viable tissue, and
• activating via said drive circuit a portion of said plurality of visual indicators to indicate said boundary.
