A first and second spectral response of light reflected from the tissue is obtained around a first wavelength and a second wavelength. Using absorption coefficients for substances at the plurality of wavelengths, concentration levels of a plurality of substances may then be determined from the spectral responses. This embodiment of the biosensor may thus be used to determine concentrations of a plurality of substances in arterial blood flow using the spectral response."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for health monitoring using a non-invasive, multi-band biosensor","description":"A biosensor includes a PPG circuit that emits light directed at living tissue at a plurality of wavelengths.
