Abstract
Apparatus for detecting the position of the mechanical interaction is disclosed. A first fabric conducting layer () has electrically conducting fibers, electrically conducting tracks () and terminals () connectable to a circuit. A second fabric layer () has conducting fibers and insulating fibers. A third separating layer () is constructed from an insulator with openings to allow conduction to occur. A forth fabric conducting layer () also has electrically conducting fibers, electrically conducting tracks () and terminals connectable to a circuit. The second fabric () is a knitted fabric having a substantially smooth back () and an irregular front (). The knitted fabric is positioned such that the irregular surface is in contact with the first conducting layer and the smooth surface is in contact with the separating layer ().
