  • Patent number: 10492701
    Abstract: A flexible conductive track arrangement has a pre-flexing condition in which the arrangement is generally planar. Conductive tracks are formed from a metal layer and they are covered above and below by insulator layers. The elongate conductive tracks are generally planar but locally corrugated perpendicularly to the general plane. This enables improved binding performance, for example to form tight windings using the conductive tracks.
