Measurement of tissue viability

An apparatus for determining a depth of a burn wound, said apparatus comprising:

• a pair of electrodes capable of forming a capacitive sensor that is configured to measure a capacitance of a region of tissue proximate to said pair of electrodes,
• a drive circuit electronically coupled to said capacitive sensor,
• 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 said capacitive sensor via said drive circuit,
• comparing said information to a data array comprising pairs of capacitances and depths of burns, and
• determining the depth of the burn wound associated with said measured capacitance.

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

• a plurality of electrodes embedded on a substrate configured to be placed over a portion of an area of tissue that includes said wound, wherein pairs of said electrodes are capable of forming a capacitive sensor that is configured to measure a capacitance of a region of tissue proximate to said capacitive sensor,
• a projector capable of projecting a visual indicator onto said area of tissue that includes said wound,
• a drive circuit electronically coupled to said plurality of electrodes and said projector,
• 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 one or more of said formed capacitive sensors,
• determining a first boundary between a first type of tissue and a second type of tissue, and causing said projector to project said visual indicator to indicate said boundary.
