摘要：
Techniques are described for detecting erythema caused by wearable devices. In various embodiments, a wearable device (104) may include light source(s) (106) to emit light at multiple wavelengths； light sensor(s) (108) to receive light reflected from tissue (100) of an individual that wears the wearable device； and logic (110) configured to: operate the light source(s) to emit light at multiple wavelengths； receive a signal generated by the light sensor(s), wherein the signal is generated by the light sensor(s) in response to detection of light reflected from the tissue； analyze the signal to determine a first metric from a first wavelength of the light reflected from a first depth of the tissue and a second metric from a second wavelength of the light reflected from a second depth of the tissue； identify a correlation between the first and second metrics； and provide output indicative of tissue erythema based on the correlation.
