Abstract

An electrode for electrostimulation includes an electric path having a storage structure for an electrolyte which comprises a front side for placing the electrode onto the skin of a living being and a rear side for making electric contact, at least one electrically conductive contacting structure, and an electric pad comprising at least one barrier structure for preventing a lateral flow of electrolytes.

Claims

1. An electrode for electrostimulation, comprising an elastic pad having a storage structure for an electrolyte, a front side for placing the electrode onto skin of a living being and a rear side for making electric contact, and at least one electrically conductive contacting structure, wherein said elastic pad comprises at least one barrier structure for preventing a lateral flow of electrolyte.

2. The electrode according to claim 1, wherein said elastic pad is segmented into at least two subareas by the at least one barrier structure.

3. The electrode according to claim 2, wherein each subarea of said elastic pad comprises its own electrically conductive contacting structure.

4. The electrode according to claim 2, wherein all subareas of said elastic pad comprise a common electrically conductive contacting structure.

5. The electrode according to claim 1, wherein the barrier structure encloses an edge region of said elastic pad.

6. The electrode according to claim 1, wherein the at least one barrier structure comprises a groove-like depression between two adjacent subareas.

7. The electrode according to claim 1, wherein said elastic pad comprises a foamed elastomer.

8. The electrode according to claim 7, wherein the storage structure comprises an open-pore foamed elastomer.

9. The electrode according to claim 7, wherein the at least one barrier structure comprises a region of said elastic pad of non-foamed elastomer.

10. The electrode according to claim 1, wherein the at least one barrier structure comprises several of at least partially interconnected material strands arranged one above the other.

11. The electrode according to claim 10, further comprising at least two mutually intersecting barrier structures formed in such a way that material strands of a first storage structure and material strands of a second storage structure intersecting said first storage structure in an intersecting region are arranged alternately one above the other, and wherein mutually contacting material strands of said first storage structure and said second storage structure are connected to one another in the intersection region.

12. The electrode according to claim 9, wherein regions of non-foamed elastomer of said elastic pad project beyond a surface of the storage structure forming the front side of said elastic pad.

13. The electrode according to claim 1, wherein said elastic pad comprises a continuous rear side layer of non-foamed elastomer or closed-pore foamed elastomer on the rear side.

14. The electrode according to claim 1, wherein said elastic pad on the rear side comprises a rear side layer of mutually intersecting material strands, which are connected to one another in an intersection region.

15. The electrode according to claim 1, wherein said storage structure is electrically conductive.

16. The electrode according to claim 1, wherein the at least one barrier structures is electrically non-conductive.

17. The electrode according to claim 1, wherein said elastic pad comprises a circumferential elastic collar for securing said elastic pad to said electrically conductive contacting structure.

18. The electrode according to claim 1, wherein said electrically conductive contacting structure comprises at least one contact element projecting into said elastic pad.

19. The electrode according to claim 7, wherein the at least one barrier structure comprises a region of said elastic pad of closed-pore foamed elastomer.

20. The electrode according to claim 19, wherein regions of closed-pore foamed elastomer of said elastic pad project beyond a surface of the storage structure forming the front side of said elastic pad.
