Abstract

An embroidered electrode (10) consists of embroidered elements (12, 13, 14) of electrically conductive thread sewn on a backing material (11). Within a given element the orientation of stitching is selected to be parallel to the direction in which the element extends.

Claims

1. An electrode including an embroidered element comprising electrically conductive thread embroidered onto a backing characterised in that the element comprises a first_portion in which the thread is stitched with an orientation such that thread direction is substantially parallel with a first direction of electrical conduction and a second portion in which the thread is stitched with an orientation such that thread direction is substantially parallel with a second direction of electrical conduction, the first and second portions contacting in at least one location.

8. An embroidered electrode in accordance with claim 1 wherein the electrically conductive thread is silverised polyamide.

9. A garment or accessory comprising an embroidered electrode in accordance with claim 1.

10. A device comprising an embroidered electrode in accordance with claim 1.

2. An embroidered electrode comprised of electrically conductive thread stitched on a backing material to form one or more embroidered element wherein said electrode comprises a primary embroidered element and one or more further embroidered element extending from a portion of the primary element,

wherein the primary embroidered element forms a peripheral electrode component and at least one of the further embroidered elements extends within the periphery described by the peripheral component from one portion of the primary element to another portion of the primary element.

3. An embroidered electrode in accordance with claim 2 wherein the primary embroidered element is arranged to loop back on itself.

4. An embroidered electrode in accordance with claim 2 wherein the at least one further embroidered element extends towards a portion of the primary element.

5. An embroidered electrode in accordance with claim 2 wherein a portion of one or more of the embroidered elements is produced from the electrically conductive thread which is stitched with an orientation selected to optimise performance of the electrode.

6. An embroidered electrode in accordance with claim 2 wherein at least one of the further embroidered elements intersects and crosses over another one of the further embroidered elements.

7. An embroidered electrode of claim 5 wherein the orientation of the stitching is selected such that thread direction is substantially parallel with the required direction of electrical conduction in the locality of the portion.

11. An embroidered electrode in accordance with claim 2 wherein the electrically conductive thread is silverised polyamide.

12. A garment or accessory comprising an embroidered electrode in accordance with claim 2.

13. A device comprising an embroidered electrode in accordance with claim 2.
