Patent ID: 11096608

Abstract:
The present disclosure relates to devices and methods for non-invasive measuring of analytes. At least one embodiment relates to a wearable system for non-invasive measuring of a concentration of an analyte in skin tissue. The wearable system includes an integrated circuit that includes a first optical unit. The first optical unit includes a Raman spectrometer. The first optical unit also includes an OCT spectrometer and an interferometer optically coupled to the OCT spectrometer or an infrared (IR) spectrometer. The first optical unit additionally includes a light coupler. The wearable system further includes a first light source for performing Raman spectroscopy. The wearable system additionally includes a second light source for performing OCT spectroscopy or IR spectroscopy. Still further, the wearable system includes read-out electronics to determine an optical model of the skin tissue based on the spectroscopic data and to determine the concentration of the analyte.
