Abstract
A nondispersive infrared (NDIR) micro-optics sensor package is described that includes one or more light sources, a photodetector, and control circuitry coupled to the one or more light sources to non-invasively measure blood alcohol concentration, such as without utilizing ex vivo bodily fluids for the measurements. Additionally, a mobile phone device configured to measure blood alcohol concentration is described that includes a mobile phone system and an NDIR micro-optics sensor package as disclosed above. Further, a process for measuring alcohol content within a subject is described.
