Abstract

A strap band including a flexible wire bus having electrodes and wires coupled with the electrodes is described. The wire bus may be encapsulated in the strap band by a molding process. The wire bus may determine electrode positions relative to each other and other structure coupled with the strap band. The strap band may be coupled with a device that includes circuitry that drives signals on to some of the electrodes and receives signals from non-driven electrodes. The electrode spacing and strap band dimensions may be selected to form a strap band that may accommodate a wide range of user body sizes for a target region the electrodes are positioned in contact with.

Claims

1. A system, comprising:

a strap band including an encapsulated wire bus having a plurality of electrodes connected with the wire bus, the wire bus including wires, each wire connected with one of the plurality of electrodes, an upper surface of each electrode is sealed by a material of the strap band and extends outward of an inner surface of the strap band;

a band;

fastening hardware coupled with the band and with the strap band; and

a device including circuitry coupled with the wires, the band and the strap band coupled to the device at opposing ends of the device.

2. The system of claim 1, wherein the fastening hardware includes a buckle including an electrode gap, the buckle operative to slide along the strap band, the electrode gap configured to have a width wider that a dimension of the plurality of electrodes so that the no portion of the buckle comes into contact with electrodes.

3. The system of claim 1, wherein the buckle is made from an electrically conductive material.

4. The system of claim 1, wherein each electrode includes an arcuate surface that extends outward of the inner surface by a distance of approximately 1.5 mm.

5. The system of claim 1, wherein the plurality of electrodes includes two pairs of adjacent electrodes, the adjacent electrodes in each pair are spaced apart from each other by a distance of approximately 4.0 mm.

6. The system of claim 5, wherein the distance comprises an edge-to-edge distance.

7. The system of claim 1, wherein the plurality of electrodes includes two pairs of adjacent electrodes, and innermost electrodes in each pair are spaced apart from each other by a distance of approximately 31.5 mm.

8. The system of claim 7, wherein the distance comprises an edge-to-edge distance.

9. The system of claim 1, wherein the plurality of electrodes includes two pairs of adjacent electrodes, and innermost electrodes in each pair are spaced apart from each other by a distance of approximately 36.0 mm.

10. The system of claim 7, wherein the distance comprises a center-to-center distance.

11. The system of claim 1, wherein the circuitry electrically couples two or more of the plurality of electrodes to driver circuitry and couples another two or more of the plurality of electrodes to pickup circuitry.

12. The system of claim 1, wherein the plurality of electrodes includes two pairs of adjacent electrodes, a first outermost electrode in a first of the two pairs is positioned a distance of approximately 32 mm from the device, and a second outermost electrode in a second of the two pairs is positioned a distance of approximately 5.5 mm from a distal end of the strap band.

13. The system of claim 1, wherein the device include an arcuate inner surface.

14. The system of claim 1, wherein the strap band, the band or both are made from a thermoplastic elastomer material.

15. The system of claim 1, wherein each electrode has a square shape with dimensions of approximately 4.5 mm on a side.

16. An apparatus, comprising:

a strap band; and
