Abstract

Claims (28)

1. A method of manufacturing a wearable ring device configured to be worn on a finger of a user, comprising:

constructing an external housing that has an exterior surface, an internal surface, a first sidewall, and a second sidewall, wherein the internal surface, the first sidewall, and the second sidewall define an internal space of the external housing;

inserting a curved battery, a printed circuit board, and one or more components into a curved perimeter of the internal space of the external housing;

applying an internal potting to at least partially fill the internal space of the external housing and cover the curved battery, the printed circuit board, and the one or more components, wherein the internal potting adheres to the external housing; and

polymerizing the internal potting, wherein at least a layer of the internal potting forms an interior surface of the wearable ring device that is configured to contact tissue of the user when the wearable ring device is worn by the user,

wherein the external housing and the internal potting form a housing for the wearable ring device, wherein the housing has an interior diameter between 12 mm and 24 mm, an exterior diameter between 18 mm and 30 mm, a width between 3 mm and 8 mm, and a thickness between 1.5 mm and 3 mm.

2. The method of claim 1 , wherein the internal potting is made of one or more of silicone, epoxy, or polyester resin.

3. The method of claim 1 , wherein the internal potting is in liquid or gelatinous form when it is applied to at least partially fill the internal space and solidifies after polymerizing.

4. The method of claim 1 , wherein the curved battery is disposed in a first portion of the curved perimeter of the internal space of the external housing, and

wherein the printed circuit board is electrically coupled with the curved battery and disposed in a second portion of the curved perimeter of the internal space of the external housing, wherein the first portion and the second portion of the curved perimeter of the internal space are different regions of the wearable ring device.

5. The method of claim 1 , wherein the printed circuit board includes a stiffener element to prevent the printed circuit board from being removed or shifting within the internal space while the internal potting is applied.

6. The method of claim 1 , wherein the printed circuit board is held in place within the internal space while the internal potting is applied.

7. The method of claim 1 , wherein the internal surface, the first sidewall, and the second sidewall form a C-shaped cross section for the external housing.

8. The method of claim 1 , wherein the external housing is made of metallic alloy comprising one or more of stainless steel, tungsten, carbide, titanium alloy, silver, platinum, or gold.

9. A method of manufacturing a wearable ring device configured to be worn on a finger of a user, comprising:

constructing an external housing that has an exterior surface, an internal surface, a first sidewall, and a second sidewall, wherein the internal surface, the first sidewall, and the second sidewall define an internal space of the external housing;

inserting a battery, a printed circuit board, and one or more components into a curved perimeter of the internal space of the external housing;

applying at least an epoxy to at least partially fill the internal space of the external housing and cover the battery, the printed circuit board, and the one or more components, wherein the epoxy adheres to the external housing; and

solidifying the epoxy, wherein at least a layer of solidified epoxy forms an interior surface of the wearable ring device that is configured to contact tissue of the user when the wearable ring device is worn by the user,

wherein the external housing and the solidified epoxy form a housing having a width between 3 mm and 8 mm, and a thickness between 1.5 mm and 3 mm.

10. The method of claim 9 , wherein the housing further has an interior diameter between 12 mm and 24 mm and an exterior diameter between 18 mm and 30 mm.

11. The method of claim 9 , wherein the epoxy is in liquid or gelatinous form when it is applied to at least partially fill the internal space.

12. The method of claim 9 , wherein the battery is disposed in a first portion of the curved perimeter of the internal space of the external housing, and

wherein the printed circuit board is electrically coupled with the battery and disposed in a second portion of the curved perimeter of the internal space of the external housing, wherein the first portion and the second portion of the curved perimeter of the internal space are different regions of the wearable ring device.

13. The method of claim 9 , wherein the printed circuit board includes a stiffener element to prevent the printed circuit board from being removed or shifting within the internal space while the epoxy is applied.

14. The method of claim 9 , wherein the printed circuit board is held in place within the internal space while the epoxy is applied.

15. The method of claim 9 , wherein the internal surface, the first sidewall, and the second sidewall form a C-shaped cross section for the external housing.

16. The method of claim 9 , wherein the external housing is made of metallic alloy comprising one or more of stainless steel, tungsten, carbide, titanium alloy, silver, platinum, or gold.
