Abstract: The present invention includes an asymmetric inductive band that preferably has a conductor affixed from a first edge of a conductor substrate and looped across said substrate. A first and a second section of the conductor preferably is formed having “hairpin-like” features at some or all intermediate endpoints, or pivot locations, at discrete points along the length thereof. In addition, the first and the second section are arranged in an asymmetric relation to each other and, in general, each, of the hairpin-like features do not preferably directly oppose another of said features. The hairpins are preferably connected by a sawtooth shaped conductor that also contributes to the change in self-inductance when stretched, in addition to the apex, or hairpin, shape of the conductor.
