The owner of the copyright rights has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the United States Patent and Trademark Office publicly available file or records, but otherwise reserves all copyright rights whatsoever.

#The technology of this disclosure pertains generally to biofeedback devices, and more particularly to biometric wearables for short, medium, and long-term data acquisition and analysis applications.

#Electronic physiological monitoring equipment has long been available in various forms. Typically, these devices are configured for fulfilling a very specific and narrow role. For example, the electrocardiograph (ECG) is used to record the pattern of depolarization of the heart muscles as blood is pumped to the lungs for oxygenation and then out to all parts of the body. The ECG produces a pattern of electrical waves that are of diagnostic importance as related to heart function.

#The technology described herein will be more fully understood by reference to the following drawings which are for illustrative purposes only:

#FIG. 1 is a perspective image of an EDA and biosensor capable ring with the biosensor module between the EDA electrodes according to an embodiment of the technology of this disclosure.

#FIG. 2A and FIG. 2B are schematic diagrams of top and bottom views (respectively) of a flex board layout for use with and fit inside the ring configuration of FIG. 1.

#1. Biosensor Hardware Configuration

#The continuous wearing biometric sensor of the present disclosure is configured to incorporate multiple sensor types into a package wearable on any finger of a user's hand.

#FIG. 1 shows a schematic diagram of an EDA triggered biosensor ring system 200 comprising an EDA sensor 36 for measuring user SNS activation, having a pair of EDA electrodes 108a and 108b configured to contact the palm side of the finger where there is the greatest density of eccrine sweat glands that respond to SNS activation, and a biosensor 202 that is located between the two EDA electrodes E1 and E2 in FIG. 2. In the embodiment shown in FIG. 1, the biosensor 202 is shown as a single module. However, other configurations may be employed.
