Abstract
A system for predicting an occurrence of a foot ulcer includes a mat configured to be stood upon by a human subject, a plurality of sensor arrays disposed on or in said mat and arranged in adjacent proximity to one another. Each sensor includes an oxygenation probe, itself including a first light source and a light detector, and a secondary probe operable to utilize the light detector of the oxygenation probe and itself including a plurality of light sources exclusive of the first light source. The plurality of light sources of the secondary probe are arranged in a pattern around the oxygenation probe. The oxygenation probe is located at the approximate geometric center of the pattern. The system further includes a control module in signal communication with the light detector, and configured to independently control emission of light from the first light source of the oxygenation probe and the plurality of light sources of the secondary probe.
