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.

Claims

1. A wearable device to measure a person'"'"'s consumption of one or more selected types of food, ingredients, and/or nutrients based on the interaction between light energy and the person'"'"'s body comprising:

a smart watch or band, wherein the smart watch or band is configured to be worn on a person'"'"'s wrist or arm, wherein the smart watch or band has six undulations around its circumference, wherein the six undulations are sinusoidal, wherein the six undulations engage sides of the person'"'"'s wrist or arm with symmetrically-opposite waves in order to avoid rotational shifting and associated biometric measurement errors which can occur with a non-undulating circular or oval watch or band, wherein a proximal portion of an undulation is the portion of the undulation which is closest to the circumferential center of the smart watch or band;

a plurality of spectroscopic sensors on the proximal portions of some or all of the six undulations, wherein the plurality of spectroscopic sensors collect data concerning the spectrum of light energy reflected from a person'"'"'s body tissue, absorbed by the person'"'"'s body tissue, and/or having passed through the person'"'"'s body tissue, and wherein the collected data is used to measure the person'"'"'s consumption of one or more selected types of food, ingredients, and/or nutrients;

a data processing unit; and

a power source.
