摘要：
The present invention pertains to a system and method for monitoring a human foot by measuring pressures applied to regions of the foot or by measuring another tissue-health related condition. A light source in the 400 nm to 1400 nm range and a detector can be embedded in a wearable article that contacts tissue while in use, spaced 200 μm to 1 cm apart, and measure a tissue hemoglobin condition. A pressure-sensing array may be read by a low-power control circuit, and a power source can be incorporated in the article. An external processing unit wirelessly coupled to the control circuit can relate pressures measured with counts that are associated with injury risk, and an alert system can notify a patient if the counts exceed a predetermined threshold. A relationship between pressure experienced by a region of tissue and the risk of ulcer development in that region may be derived.
