Abstract

A health monitoring device is provided, and may be used in population health monitoring and disease tracing, as well as for individual subject health purposes. The health monitoring device comprises a triboelectric nanogenerator (TENG) for generating and storing electrical energy from mechanical activity of a user. The device provides a continuous and uninterrupted stream of physiological data received at a surface of the device in contact with a surface of the user. The triboelectric nanogenerator is a paper-based device comprising a paper-based material layer and a polydimethylsiloxane/polytetrafluoroethylene (PDMS/PTFE) material layer, each on a copper film. The device has enhanced sensitivity to motion, providing an improved device capable of converting small amounts of movement into electrical energy, and of recording and transmitting data of small physiological changes of a user to a receiver. The device is lithium free, and eliminates the necessity of recharging.

First claim

What is claimed is:

1. A health monitoring device comprising:
a wearable device having a surface suitable for being in contact with a skin surface of a user;
a triboelectric nanogenerator (TENG) positioned on a portion of the surface capable of generating electrical energy from mechanical energy;
a means for transmitting electrical energy generated by the TENG to the device surface in contact with the skin surface;
a means for continuously measuring physiological data, and
a means for transmitting physiological data received at the device surface in contact with the user to a receiver,

wherein the physiological data provides for classifying the user as a high disease symptom user or a low disease symptom user as compared to an average non-disease user symptom reference.

2. The health monitoring device of claim 1 , wherein the TENG comprises a paper-based material layer.

3. The health monitoring device of claim 2 , wherein the paper-based material layer includes a copper film provided thereon.

4. The health monitoring device of claim 2 , wherein the TENG further comprises a polymer-based material layer.

5. The health monitoring device of claim 4 , wherein the polymer-based material layer includes a copper film provided thereon.

6. The health monitoring device of claim 5 , wherein the polymer-based material layer comprises a Polydimethylsiloxane/Polytetrafluoroethylene (PDMS/PTFE) copolymer composite.

7. The health monitoring device of claim 1 , wherein the physiological data is transmitted in an uninterrupted stream of data to the receiver.

8. A health monitoring system configured to receive physiological data from one or more users, said system comprising:
a health monitoring device comprising:
a wearable device having a surface suitable for being in contact with a skin surface of a user;
a triboelectric nanogenerator (TENG) positioned on a portion of the surface capable of generating electrical energy from mechanical energy received;
a means for transmitting electrical energy generated by the TENG to the device surface in contact with the skin surface;
a means for continuously measuring physiological data, and
a means for transmitting physiological data received at the device surface in contact with the user;
a mobile receiver device configured to receive the transmitted physiological data from said health monitoring device associated with the user, and
one or more servers configured to store and/or process the physiological data from said health monitoring device associated with the user, wherein the physiological data is transmitted from the mobile receiver device to the one or more servers by means of a network,

wherein the physiological data provides for classifying the user as a high disease symptom user or a low disease symptom user as compared to an average non-disease user symptom reference.

9. The health monitoring system of claim 8 , wherein the TENG comprises a paper-based material layer.

10. The health monitoring system of claim 9 , wherein the TENG further comprises a polymer-based material layer.

11. The health monitoring system of claim 10 , wherein each of paper-based material layer and the polymer-based material layer includes a copper film provided thereon.

12. The health monitoring system of claim 10 , wherein the polymer-based material layer comprises a Polydimethylsiloxane/Polytetrafluoroethylene (PDMS/PTFE) copolymer composite.

13. A wearable health monitoring device comprising:
a triboelectric nanogenerator (TENG) configured for contact with a user's skin and capable of generating electrical energy from mechanical energy, said TENG comprising a paper-based material layer and a polymer-based material layer;
a band configured for securing the wearable health monitoring device to the user;
a display screen for displaying information to the user; and
a battery configured for powering the wearable health monitoring device;
wherein the TENG is configured to charge the battery by converting mechanical energy produced by body motion of the user to electrical energy, and
wherein the TENG is further configured as a sensor for collecting physiological information about the user, and
wherein the physiological information about the user provides for classifying the user as a high disease symptom user or a low disease symptom user as compared to an average non-disease user symptom reference.

14. A method for tracking and/or monitoring a subject within a population for disease symptoms associated with a defined disease comprising:
transmitting a simultaneous stream of physiological data from one or more subjects collected from a wearable health monitoring device placed on a skin surface of a subject, said physiological data being transmitted to one or more servers configured to store and/or process the physiological data from said health monitoring device, said wearable device comprising:
a wearable device having a surface suitable for being in contact with a skin surface of a user;
a triboelectric nanogenerator (TENG) positioned on a portion of the surface, capable of generating electrical energy from mechanical energy;
a means for transmitting electrical energy generated by the TENG to the device surface in contact with the skin surface;
a means for continuously measuring physiological data, and
a means for transmitting physiological data received at the device surface in contact with the subject to a designated disease tracking entity; and
transmitting the physiological data from the device to a disease tracking entity by means of a network to the designated disease tracking entity; and
identifying and classifying a subject as a high disease symptom subject or a low disease symptom subject as compared to an average non-disease subject symptom reference,

wherein said classification of the subject provides for the tracking and/or monitoring of the subject.

15. The method of claim 14 wherein the disease tracking entity is a hospital, skilled nursing facility, governmental entity, or population health entity.

16. The method of claim 14 wherein a geographical location of the high disease symptom subjects and the low disease symptom subjects is provided to the disease tracking entity.

17. The method of claim 14 wherein the disease symptoms are associated with a viral disease or a bacterial disease.

18. The method of claim 17 wherein the viral disease is Covid-19.
