1. 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 capacitances associated with depths of burns, wherein pairs of capacitances and depths of burns are made, wherein each pair comprises a single capacitance and its corresponding depth of burn, and
determining the depth of said burn wound associated with said measured capacitance.
