Patent attributes
The present invention relates to a detector constructed from electrically conducting fabric and configured to present a varying electrical characteristic in response to a mechanical interaction. The detector comprises a first conducting layer (401) which is displaced from a second conducting layer (402) such that conduction between the layers results when the layers are mechanically forced together. In addition, the first of the layers has a plurality of lengths of conductive yarn and a plurality of lengths of non-conductive yarn machined therein, such that at least one length of conductive yarn is electrically isolated from another of the lengths of conductive yarn and the conducting yarns in the first of the layers are electrically grouped to define a plurality of identifiable rows. Each identifiable row has a respective electrical conductor; and define specific regions of the detector.
