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 adjacent spaced conductors extending along the band in a flexible pattern serving as components of the respiration sensing subsystem; and

a flexible moisture repellant compound permeating the band front to back in the stretchable material of the band between the pair of adjacent spaced conductors only, said compound 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. The respiration sensing subsystem of claim 1 in which the band is made of a stretchable fabric material.

5. A respiration sensing subsystem comprising:

a band made of stretchable material;

a pair of adjacent spaced conductors extending along the band in a flexible pattern serving as components of the respiration sensing subsystem; and

a flexible moisture repellant compound impregnated into and permeating the band front to back in the stretchable material of the band between the pair of adjacent spaced conductors only to avoid adverse affects on stretchability of the band, said compound serving as a dielectric material between the spaced conductors for measuring respiration and for reducing dynamic range of measured values as the band stretches and impedance between the conductors varies.

6. A respiration sensing subsystem comprising:

a band made of stretchable material;

a pair of adjacent spaced insulated conductors extending along the band in a flexible pattern serving as components of the respiration sensing subsystem; and

a flexible moisture repellant compound between said spaced insulated conductors serving as the dielectric between said conductors instead of air.
