Wearable biometric monitoring devices and methods for determining if wearable biometric monitoring devices are being worn

1. A method of detecting if a biometric monitoring device is being worn by a subject, wherein the biometric monitoring device includes a physiological sensor and at least one processor, the method comprising:

creating a first signature by assessing sensor readings from the physiological sensor at a first prior time, in response to the subject indicating at the first prior time that the device is being worn;

creating a second signature by assessing sensor readings from the physiological sensor at a second prior time, in response to the subject indicating at the second prior time that the device is not being worn;

analyzing signals from the physiological sensor to detect a signature unique to the subject wearing the biometric monitoring device; and

determining if the detected signature is the first signature associated with the biometric monitoring device being worn or the second signature associated with the biometric monitoring device not being worn.

2. The method of claim 1 , wherein the subject indicates that the biometric monitoring device is being worn at the first prior time and that the biometric monitoring device is not being worn at the second prior time via a user interface of a remote device in communication with the at least one processor.

3. The method of claim 2 , wherein the remote device is one of the following: a smart phone, a computer, a smart pad, a cloud-based processing system, a wearable accessory, a control box, a medallion, a smartwatch, smart glasses.

4. The method of claim 2 , wherein the remote device is in wireless communication with the at least one processor.

5. The method of claim 1 , wherein the biometric monitoring device is an earbud, an earpiece, or a headset.

6. The method of claim 1 , wherein the biometric monitoring device is a hearing aid.

7. The method of claim 1 , wherein the biometric monitoring device is integrated within a wrist strap, a wrist watch, an ankle bracelet, a headband, an armband, a patch, or clothing.

8. The method of claim 1 , wherein the physiological sensor comprises a photoplethysmography (PPG) sensor configured to detect and/or measure heart rate information from the subject.

9. A biometric monitoring device configured to be worn by a subject, the device comprising:

a physiological sensor configured to detect and/or measure physiological information from the subject; and

at least one processor configured to:

create a first signature by assessing sensor readings from the physiological sensor at a first prior time, in response to the subject indicating at the first prior time that the device is being worn;

create a second signature by assessing sensor readings from the physiological sensor at a second prior time, in response to the subject indicating at the second prior time that the device is not being worn;

analyze signals from the physiological sensor to detect a signature unique to the subject wearing the biometric monitoring device; and

determine if the detected signature is the first signature associated with the biometric monitoring device being worn or the second signature associated with the biometric monitoring device not being worn.

10. The biometric monitoring device of claim 9 , wherein the at least one processor is configured to communicate with a remote device, and wherein the subject indicates that the biometric monitoring device is being worn at the first prior time and that the biometric monitoring device is not being worn at the second prior time via a user interface of the remote device.

11. The biometric monitoring device of claim 10 , wherein the remote device is one of the following: a smart phone, a computer, a smart pad, a cloud-based processing system, a wearable accessory, a control box, a medallion, a smartwatch, and smart glasses.

12. The biometric monitoring device of claim 10 , wherein the at least one processor is configured to communicate wirelessly with the remote device.

13. The biometric monitoring device of claim 9 , wherein the biometric monitoring device is an earbud, an earpiece, or a headset.

14. The biometric monitoring device of claim 9 , wherein the biometric monitoring device is a hearing aid.

15. The biometric monitoring device of claim 9 , wherein the biometric monitoring device is integrated within a wrist strap, a wrist watch, an ankle bracelet, a headband, an armband, a patch, or clothing.

16. The biometric monitoring device of claim 9 , wherein the physiological sensor comprises a photoplethysmography (PPG) sensor configured to detect and/or measure heart rate information from the subject.
