1. A medical device configured to couple to a body, the medical device comprising:
a substrate configured to couple to a user's skin;
a first illuminator configured to emit light at a first range of wavelengths;
a second illuminator configured to emit light at a second range of wavelengths, wherein the second range of wavelengths is different from the first range of wavelengths
a photodetector assembly comprising an array of quantum dot photodetectors, wherein the array of quantum dot photodetectors includes (i) a first quantum dot photodetector of a first size and configured to absorb light in the first range of wavelengths and (ii) a second quantum dot photodetector of a second size and configured to absorb light in the second range of wavelengths, wherein the first size is different from the second size; and
a controller electronically coupled to the photodetector assembly, the first illuminator, and the second illuminator and configured to:
deactivate the first quantum dot photodetector and the first illuminator when the second quantum dot photodetector and the second illuminator are activated; and
deactivate the second quantum dot photodetector and the second illuminator when the first quantum dot photodetector and the first illuminator are activated.
