Abstract

A respiration sensing subsystem includes a band made of stretchable material and a pair of spaced conductors extending along the band in a flexible pattern. A moisture repellant compound is added to the stretchable material of the band between the pair of spaced conductors.

Claims

1. A respiration sensing subsystem comprising:

a band made of stretchable material;

a pair of spaced conductors extending along the band in a flexible pattern; and

a flexible moisture repellant compound in the stretchable material of the band between the pair of spaced conductors serving as a dielectric material between the spaced conductors for measuring respiration as the band stretches and impedance between the conductors varies.

2. The respiration sensing subsystem of claim 1 in which the conductors are insulated wire integrated into the band.

3. The respiration sensing subsystem of claim 1 in which the flexible moisture repellant compound includes silicone.

4. A method of making a respiration sensing subsystem, the method comprising:

integrating a pair of spaced conductors in a flexible pattern into the material of a stretchable band;

detecting changes in impedance between the spaced conductors as the band stretches to sense at least one respiration parameter; and

incorporating a flexible moisture repellant compound in the stretchable material of the band serving as a dielectric between the pair of spaced conductors to prevent moisture from affecting the sensing of said at least one parameter.

5. The method of claim 4 in which the conductors are insulated wires integrated into the band.

6. The method of claim 4 in which the moisture repellant compound includes silicone.

7. A respiration sensing subsystem comprising:

a band made of stretchable material;

spaced insulated wires woven into the band extending along the band in a flexible pattern;

at least one pair of insulated wires serving to sense respiration; and

a flexible moisture repellant compound in the stretchable material of the band between the pair of insulated wires serving as a dielectric between the pair of insulated wires.

8. A method of making a respiration sensing subsystem, the method comprising:

incorporating spaced insulated wires in a flexible pattern into the material of a stretchable band;

detecting changes in impedance between at least one pair of spaced insulated wires as the band stretches to sense at least one respiration parameter; and

incorporating a moisture repellant compound in the stretchable material of the band between said pair of spaced insulated wires to prevent moisture from affecting the sensing of said at least one respiration parameter.

9. A method of making a respiration sensing subsystem, the method comprising:

integrating a pair of spaced conductors in a flexible pattern into the material of a stretchable band; and

incorporating a moisture repellant compound in the stretchable material of the band between the pair of spaced conductors to prevent moisture from affecting the sensing of a respiration parameter.
