Abstract

This is a wearable biometric device for an arm including spectroscopic sensors which project light onto an arm surface at different angles. Data from these sensors can be used to measure a person'"'"'s hydration levels, oxygen levels, glucose levels, or heart rate.

Claims

1. An arm wearable device with a close-fitting spectroscopic sensor comprising:

an attachment member which is configured to span at least a portion of a circumference of a person'"'"'s arm;

an enclosure which is part of and/or attached to the attachment member; and

a rotatable light-projecting spectroscopic sensor, wherein the sensor is rotated relative to the enclosure and wherein rotation of the sensor relative to the enclosure changes the angle at which the sensor projects light onto the surface of the person'"'"'s arm and the sensor measures the light reflected from and/or absorbed by tissue of the person'"'"'s arm.

2. The device in claim 1 wherein the attachment member is selected from the group consisting of:

strap, band, bracelet, ring, armlet, cuff, and sleeve.

3. The device in claim 1 wherein the attachment member is configured to be attached to the person'"'"'s arm by connecting two ends of the attachment member with a clasp, clip, buckle, hook, pin, plug, or hook-and-eye mechanism.

4. The device in claim 1 wherein the attachment member is configured to be attached to the person'"'"'s arm by stretching and sliding it over the person'"'"'s hand onto the arm.

5. The device in claim 1 further comprising a processor configured to analyze data from the rotatable light-projecting spectroscopic sensor to measure the person'"'"'s hydration levels.

6. The device in claim 1 further comprising a processor configured to analyze data from the rotatable light-projecting spectroscopic sensor to measure the person'"'"'s oxygen levels.

7. The device in claim 1 further comprising a processor configured to analyze data from the rotatable light-projecting spectroscopic sensor to measure the person'"'"'s glucose levels.

8. An arm wearable device with a close-fitting spectroscopic sensor comprising:

an attachment member which is configured to span at least a portion of a circumference of a person'"'"'s arm;

an enclosure which is part of and/or attached to the attachment member; and

a rotatable light-projecting spectroscopic sensor;

wherein the sensor is automatically rotated relative to the enclosure;

wherein automatic rotation of the sensor relative to the enclosure changes the angle at which the sensor projects light onto the surface of the person'"'"'s arm; and

wherein the sensor is automatically rotated to record measurements at substantially the same angle of incidence even if the enclosure is tilted with respect to the surface of the person'"'"'s wrist.

9. The device in claim 8 wherein the attachment member is selected from the group consisting of:

strap, band, bracelet, ring, armlet, cuff, and sleeve.

10. The device in claim 8 wherein a spectroscopic sensor is configured to measure the spectrum of light energy reflected from and/or absorbed by tissue of the person'"'"'s arm.

11. The device in claim 8 further comprising a processor configured to analyze data from the rotatable light-projecting spectroscopic sensor to measure the person'"'"'s hydration levels.

12. The device in claim 8 further comprising a processor configured to analyze data from the rotatable light-projecting spectroscopic sensor to measure the person'"'"'s oxygen levels.

13. The device in claim 8 further comprising a processor configured to analyze data from the rotatable light-projecting spectroscopic sensor to measure the person'"'"'s glucose levels.
