Abstract
A method, system, apparatus, and/or device to determine a condition of a user using a wearable device with a miniaturized spectrometer. The method, system, apparatus, and/or device may include: a band configured to extend at least partially around a body part of a user, the body part comprising an internal feature within the body part; a light source embedded in the band, where the light source is configured to emit light into the body part as the user wears the band; a collimator; an optical filter; and an optical sensor, where the collimator, optical sensor, or the optical filter are arranged together to form a stack embedded in the band.
