Composite elastic and wire fabric for physiological monitoring apparel
First Claim
Patent Images
1. A composite fabric construction for use in apparel of the type used for monitoring physiological parameters comprising:
- (a) an elongated band of elastic material which is stretchable in the longitudinal direction; and
(b) at least one conductive wire incorporated with said elastic fabric band in a prescribed curved pattern extending along said longitudinal direction, wherein stretching or contracting of the fabric changes the curved pattern of the wire, and thus changes the inductance of the wire.

Abstract
A fabric for use in apparel of the type used for physiological monitoring of prescribed body functions has one or more elongated bands of elastic material which is stretchable in the longitudinal direction. Each such elastic band includes at least one conductive wire affixed to or formed therein in a curved pattern. A garment and a system of the type used for physiological monitoring of prescribed body functions includes such a fabric and a monitoring unit monitoring electrical parameters of the included conductive wires.

6. A garment of the type for use in physiological monitoring of prescribed body functions comprising a fabric construction, wherein the fabric construction includes:
-
(a) an elongated band of elastic material which is stretchable in the longitudinal direction and which is incorporated into the garment in such a manner as to expand and contract responsive to the body function; and
(b) at least one conductive wire affixed to said elastic fabric band in a substantially sinusoidal pattern extending along said longitudinal directions, wherein stretching or contracting of the fabric changes the curved pattern of the wire, and thus changes the inductance of the wire.

7. A composite fabric construction for use in apparel of the type used for monitoring physiological parameters comprising:
-
(a) an elongated band or cord of elastic material which is stretchable in the longitudinal direction; and
(b) at least one conductive wire formed with said elastic fabric band or cord in a prescribed curved pattern extending along said longitudinal direction, wherein stretching or contracting of the fabric changes the curved pattern of the wire, and thus changes the inductance of the wire.
