1. A position detector constructed from fabric having a first electrically conductive fabric plane and a second electrically conductive fabric plane, whereina plurality of wires are connected to said first plane so as to establish at least one electrical potential gradient across said plane;

  • a mechanical interaction brings said first electrically conducting plane into contact with said second electrically conducting plane such that current flows at the position of said contact;

    a single wire is connected to said second plane so as to allow said current to flow; and

    the resistivity of said first plane is higher than the resistivity of said second plane so as to facilitate the establishment of a potential gradient across said first plane and to facilitate current flow through said second plane.
