Abstract
A smart ring includes a housing configured to be worn by a user. The smart ring can further include a power source disposed within the housing. The smart ring also can include a charging circuit disposed within the housing. The charging circuit can include a harvesting element configured to charge the power source. The harvesting element can be configured to convert mechanical energy to electrical energy. The smart ring also can include a device at least partially disposed within the housing. The device can be configured to draw energy from the power source. Other embodiments are disclosed.
Claims (48)
1. A smart ring comprising:
a housing configured to be worn by a user;
a power source disposed within the housing;
a charging circuit disposed within the housing, wherein the charging circuit includes a harvesting element configured to charge the power source, and wherein the harvesting element is configured to harvest energy from a motion of a portion of the user wearing the housing; and
a device at least partially disposed within the housing, wherein the device is configured to draw energy from the power source.
2. The smart ring of claim 1 , wherein:
the harvesting element comprises a piezoelectric harvesting element.
3. The smart ring of claim 1 , wherein:
the harvesting element comprises an induction coil.
4. The smart ring of claim 3 , wherein:
the induction coil includes one or more turns along a circumference of a ring-shaped housing.
5. The smart ring of claim 1 , wherein:
the harvesting element includes one or more additively manufactured components.
6. The smart ring of claim 1 , wherein:
the motion of the portion of the user comprises an arm swing.
7. The smart ring of claim 1 , wherein:
the harvesting element is configured to vibrate or oscillate in response to the motion of the portion of the user wearing the housing.
8. A smart ring comprising:
a means for housing, wherein the means for housing is configured to be worn by a user;
a means for powering, wherein the means for powering is disposed within the means for housing;
a means for charging disposed within the means for housing, wherein the means for charging includes a means for harvesting configured to charge the means for powering, and wherein the means for harvesting is configured to harvest energy from a motion of a portion of the user wearing the housing; and
a means for drawing energy from the means for powering, wherein the means for drawing energy from the means for powering is at least partially disposed within the means for housing.
9. The smart ring of claim 8 , wherein:
the means for harvesting is a means for harvesting piezoelectric energy.
10. The smart ring of claim 8 , wherein:
the means for harvesting comprises an induction coil.
11. The smart ring of claim 10 , wherein:
the induction coil includes one or more turns along a circumference of a ring-shaped housing.
12. The smart ring of claim 8 , wherein:
the means for harvesting includes one or more additively manufactured components.
13. The smart ring of claim 8 , wherein:
the motion of the portion of the user comprises an arm swing.
14. A method for operating a smart ring, the method comprising:
generating electrical energy at a charging circuit within the smart ring, wherein the charging circuit includes a harvesting element, and wherein the harvesting element is configured to harvest energy from a motion of a portion of a user wearing the smart ring;
charging a power source disposed within the smart ring by delivering the electrical energy from the charging circuit to the power source; and
causing the power source to provide power to a device disposed within the smart ring.
15. The method of claim 14 , wherein:
the harvesting element comprises a piezoelectric harvesting element.
16. The method of claim 14 , wherein:
the harvesting element comprises an induction coil.
17. The method of claim 16 , wherein:
the induction coil includes one or more turns along a circumference of the smart ring.
18. The method of claim 14 , wherein:
the harvesting element includes one or more additively manufactured components.
19. The method of claim 14 , wherein:
the motion of the portion of the user comprises an arm swing.
20. The method of claim 14 , wherein:
the harvesting element is configured to vibrate or oscillate in response to the motion of the portion of the user wearing the smart ring.
