Abstract

An electronic device is provided which can be worn on the body or implanted into the body, such as in the form of a pulse watch and/or a smartwatch and/or an implant. The electronic device includes a photoplethysmographic measuring device. A transmitter diode and a receiver diode are arranged under a window made of glass or glass ceramics. The window is implemented as a compression glass seal and/or as a fiber-optic plate.

First claim

What is claimed is:

1. An electronic device that can be worn on the body or introduced into the body, comprising:
a casing having a top and a bottom;
an inorganic support; and
at least one window made of at least one of glass or glass ceramics provided on the bottom, wherein the at least one window is fused into the inorganic support, wherein the at least one window is a compression glass seal and has a root mean square roughness value Rq of 2 nm or more.

2. The electronic device of claim 1 , wherein the inorganic support comprises at least one of a metal, glass ceramics, or opaque glass.

3. The electronic device of claim 1 , wherein the inorganic support comprises ceramics.

4. The electronic device of claim 1 , wherein the at least one window is in the form of a compression glass seal.

5. The electronic device of claim 1 , wherein the at least one window is bonded to the inorganic support by a glass solder.

6. The electronic device of claim 1 , wherein the electronic device has one window with a transmitter diode and a receiver diode arranged therebelow, so that the receiver diode receives light through the same window through which the transmitter diode emits light.

7. The electronic device of claim 1 , wherein the inorganic support has a further window comprising at least one electrical feedthrough.

8. The electronic device of claim 7 , wherein the at least one electrical feedthrough serves as a measurement electrode or is connected to a measurement electrode.

9. The electronic device of claim 1 , wherein the inorganic support has a projection in an area of the at least one window.

10. The electronic device of claim 1 , wherein the at least one window is in the form of a fiber-optic plate.

11. The electronic device of claim 1 , wherein the at least one window is a compression glass seal, which is designed such that in the event of damage craters are produced.

12. The electronic device of claim 1 , wherein the at least one window is a compression glass seal which is designed such that in the event of damage at least one of glass or glass ceramic material separated from the at least one window is powdery.

13. The electronic device of claim 1 , wherein the at least one window is a compression glass seal which has from 3 to less than 16 microdefects within a measuring section of 10 mm in length.

14. The electronic device of claim 1 , wherein at least one of the following is satisfied:
the at least one window has a fire-polished surface on a side facing away from the casing;
the fire-polished surface has a waviness value of more than 100 nm and less than 5 μm;

the at least one window has a concave surface or a convex surface on the side facing away from the casing; or
the at least one window is in the form of a filter for at least one of a receiver or a transmitter diode.

15. The electronic device of claim 1 , wherein the electronic device is a pulse watch comprising a measuring device operating on the principle of photoplethysmography.

16. The electronic device of claim 1 , wherein the at least one window has a surface on a side facing away from the casing, wherein the surface on the side facing away from the casing is at least one of a planar surface, a curved surface, a convex surface, or a concave surface.

17. An electronic device that can be worn on the body or introduced into the body, comprising:
a casing having a top and a bottom;
an inorganic support; and
at least one window made of at least one of glass or glass ceramics provided on the bottom, wherein the at least one window is fused into the inorganic support, wherein the at least one window comprises at least two windows made of at least one of glass or glass ceramics that are fused into the inorganic support, the at least two windows comprising a first window and a second window, the electronic device further comprising a transmitter diode provided below the first window and a receiver diode provided below the second window, wherein at least one of the following is satisfied:
the first window is spaced apart from the second window by an edge-to-edge spacing s and at least one of the first window or the second window has a diameter d, with a ratio s/d=2 to 7; or
the first window is spaced apart from the second window by an edge-to-edge spacing s and at least one of the first window or the second window has a height h, with a ratio s/h=1 to 3.

18. An electronic device that can be worn on the body or introduced into the body, comprising:
a casing having a top and a bottom;
an inorganic support; and
at least one window made of at least one of glass or glass ceramics provided on the bottom, wherein the at least one window is fused into the inorganic support, wherein the inorganic support consists of two parts comprising an outer metallic part surrounding an inner part that is made of ceramic or opaque glass, the outer metallic part surrounding the inner part in a ring-like manner, wherein an opening is provided in the inner part, which is sealed by the at least one window.

19. A method for producing an electronic device that can be worn on the body or introduced into the body, the electronic device comprising a casing having a top and a bottom, an inorganic support, and at least one window made of at least one of glass or glass ceramics provided on the bottom, wherein the at least one window is a compression glass seal and has a root mean square roughness value Rq of 2 nm or more, the method comprising:
fusing the at least one window into the inorganic support; and
joining the inorganic support to the casing of the electronic device.

20. A method for producing an electronic device that can be worn on the body or introduced into the body, the electronic device comprising a casing having a top and a bottom, an inorganic support, and at least one window made of at least one of glass or glass ceramics provided on the bottom, wherein the at least one window is a compression glass seal and has a root mean square roughness value Rq of 2 nm or more, and wherein the at least one window has a planar surface on a side facing away from the casing, the method comprising:
fusing the at least one window into the inorganic support; and
joining the inorganic support to the casing of the electronic device.
