Wearable Device for the Arm with Close-Fitting Biometric Sensors

摘要

This invention is a wearable device for an arm with a plurality of close-fitting biometric sensors. These sensors can be spectroscopic sensors which project light onto an arm surface at different angles. Alternatively, these sensors can be electromagnetic energy sensors which measure tissue impedance, resistance, conductivity, or permittivity. These sensors can be on the circumference-center-facing wall of an elastic fluid, gel, or gas filled member. Data from these sensors can be used to measure a person's hydration levels, oxygen levels, glucose levels, or heart rate.

主权项

1. A wearable device for the arm with a plurality of close-fitting spectroscopic sensors comprising:
an attachment member which is configured to span at least a portion of the circumference of a person's arm; an enclosure which is part of and/or attached to the attachment member; a first spectroscopic sensor in the enclosure which is configured to project a beam of light onto the arm surface at a first angle relative to the enclosure; and a second spectroscopic sensor in the enclosure which is configured to project a beam of light onto the arm surface at a second angle relative to the enclosure, wherein the first angle differs from the second angle by at least 10 degrees.
