Abstract

The present invention relates generally to an electrode assembly including a thin, low thickness snap for use, for example, in a heart rate monitoring. The electrode assembly can come in the form of a kit with multiple pieces or in an assembled form. The electrode assembly includes two electrodes with respective snaps connected by a non-stretchable material portion. The electrode assembly can be easily integrated into a garment with minimal interference in the usability of the garment itself. Additionally, the present invention relates to a garment having integrated therein an electrode assembly.

First claim

The invention claimed is:

1. An electrode assembly comprising;
a first electrode having an upper cap portion of a first snap on one side,
a second electrode having an upper cap portion of a second snap on one side,
said upper cap portions each having a respective recess forming at least a portion of a side wall of a socket region of each snap for receiving a male end of a telemetric device and comprising an outer flange region which at least partially surrounds the recess,
a linking member having a first base portion of the first snap and a second base portion of the second snap separated by a non-stretchable material portion,
said first and second electrodes being coupleable to the linking member by the respective first and second base portions, wherein
for each electrode, the outer flange region of the upper cap portion is depressed towards said base portion to reduce a thickness of the snap and to integrate said snap in a garment with a top surface of said upper cap portion flush with a material layer of said garment disposed on top of the electrode.

2. The electrode assembly according to claim 1 , wherein the upper cap portions further each comprise a conductive wire spring mechanically affixed to the upper cap portion.

3. The electrode assembly according to claim 2 , wherein the upper cap portions further each comprise at least one lip which mechanically couples the conductive wire spring to its respective upper cap portion.

4. The electrode assembly according to claim 2 , wherein the upper cap portions further each comprise at least one lip which mechanically couples the conductive wire spring to its respective upper cap portion and said at least one lip is a tab cut from the outer flange region of said upper cap portion and is bent towards the recess.

5. The electrode assembly according to claim 1 , wherein the non-stretchable material portion is flexible.

6. The electrode assembly according to claim 1 , wherein the first and second base portions are rigid.

7. The electrode assembly according to claim 1 , wherein the first and second base portions have a first rigidity and wherein the non-stretchable material portion has a second rigidity lower than the first rigidity.

8. The electrode assembly according to claim 1 , wherein the first base portion, second base portion and the non-stretchable material portion are made of the same material.

9. The electrode assembly according to claim 1 , wherein the first base portion; and second base portion are made of a first material and the non-stretchable material portion is made of a second material having a lower rigidity than that of the first material.

10. The electrode assembly according to claim 1 , wherein non-stretchable material portion has structural elements which reduce its rigidity compared to the first and second base portions.

11. The electrode assembly according to claim 10 , wherein said structural elements are selected from the group of: slits, gaps in the material, valleys in the material, holes in the material, and areas with material of less thickness than other areas.

12. The electrode assembly according to claim 1 , wherein the first base portion, second base portion and the non-stretchable material portion form an integral member.

13. The electrode assembly according to any of the preceding claims, wherein the first base portion and the second base portion are mechanically or chemi-mechanically bonded to the non-stretchable material portion.

14. The electrode assembly according to claim 1 , wherein each outer flange region of said upper cap portion comprises a plurality of openings for securing the upper cap portion to the respective electrode and base portion of said linking member, each electrode has a complementary set of openings, and each base portion has a complementary set of extensions for fitting through the openings in the upper cap portions and the respective electrodes for securing the assembly.

15. The electrode assembly according to claim 1 , wherein the electrode assembly is a single unit, and wherein the first electrode and the second electrode are coupled to their respective first and second base portions of the linking member.

16. The electrode assembly according to claim 1 , wherein the electrode assembly is a kit and at least one of the following pieces is not coupled to its respective portion: the first electrode, the upper cap portion of the first electrode, the second electrode, the upper cap portion of the second electrode and the linking member.

17. A garment having integrated therein an electrode assembly comprising;
a first electrode having an upper cap portion of a first snap on one side,
a second electrode having an upper cap portion of a second snap on one side, and
a linking member having a first base portion of said first snap and a second base portion of said second snap separated by a non-stretchable material portion,
said first and second electrodes being coupleable to the linking member by respective first and second base portions, wherein
for each electrode, said upper cap portions having a recess forming a socket region of the respective snap and comprising an outer flange region which at least partially surrounds the recess, said outer flange region being depressed towards said base portion to reduce a thickness of the snap and to integrate said snap in said garment having a top surface of said upper cap portion flush with a material layer of said garment disposed on top of each electrode.
