    Abstract: The described embodiments relate to a sensor patch that can be temporarily removed and re-applied in the same location using a side element of the sensor patch. The side element can be folded onto the sensor patch when the sensor patch is adhered to an object such as an appendage of a person. The side element can be unfolded and adhered to the appendage in order to preserve the placement of the sensor patch on the appendage. In this way, maintenance such as cleaning can be performed on the area where the sensor patch is located without having to dispose of the sensor patch. Once maintenance is completed, the side element can be folded back onto a surface of the sensor patch until maintenance is to be performed again.

    Abstract: 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.
