Patent ID: 8034001

Claim:
A physiological sensor for monitoring a subject, comprising: a supporting elastic material adapted to be arranged on a body part of the monitored subject and, when so arranged, stretchable through an operating range of stretch by expansion and contraction of said underlying body part; two sensor conductors, each of said sensor conductors being operably affixed to said elastic material in a pattern comprising repeated unit waves that stretch and contract with said supporting elastic material, wherein at least one unit wave is configured to have legs that are substantially parallel, wherein the at least one unit wave is configured such that the legs of the unit wave remain substantially parallel throughout an operating range of stretch, and wherein each sensor conductor has an external contact point; and a bridging connection connecting the two sensor conductors, wherein the bridging connection is arranged so that the two bridged sensor conductors are electrically continuous, wherein the two sensor conductors form a loop configuration having a bridged end and an external contact end, and wherein the external contact points of the two sensor conductors are located at the external contact end of the loop.
