Abstract
This is a wearable device to measure a person's food consumption based on the interaction between light energy and body tissue comprising: a wearable spectroscopic sensor that collects data concerning the spectrum of light energy reflected from body tissue or having passed through body tissue; a data processing unit; and a power source. Spectroscopic sensor data is analyzed to measure consumption of selected types of food, ingredients, and/or nutrients. This device can be embodied in a finger ring, smart watch, wrist band, wrist bracelet, armlet, cuff, or sleeve with close-fitting spectroscopic sensors.
