Abstract:
1. An asymmetric inductive band for monitoring respiration in a subject, the asymmetric inductive band comprising: an elongate conductor having a first portion and a second portion, said first portion and said second portion being arranged in an asymmetric relationship to each other; a processor receiving a signal from the elongate conductor and outputting a respiration signal; each of said first portion and said second portion having a series of hairpin features at a plurality of positions in a lengthwise direction thereof, said hairpin features being connected by sawtooth-shaped intermediate sections; said hairpin features each having a first straight leg portion, a second straight leg portion, and an apex portion connecting the first straight leg portion to the second straight leg portion, the first straight leg portion and the second straight leg portion being closely spaced from each other; and the hairpin features of the first portion and the hairpin features of the second portion being disposed in a spaced-apart relationship and overlapping each other along a common longitudinal axis disposed between the first portion and the second portion of the elongate conductor; wherein the asymmetric inductive band is distensible.
