Abstract
A method, system, apparatus, and/or device to determine a condition of a user using multiple sensors. The method, system, apparatus, and/or device may include: a band configured to extend at least partially around a body part of a user having a subdermal feature within body part; a light configured in the band to emit light into the body part; a miniaturized spectrometer positioned in the band to press against the body part to receive the light, where the miniaturized spectrometer comprises: an optical filter configured to isolate a relevant constituent wavelength of the light; a collimator configured to collimate the light; and an optical sensor configured to detect an intensity of the relevant constituent wavelength; and an impedance sensor integrated into the band and configured to be positioned against a same side of the body part as the miniaturized spectrometer.
