Abstract:
A position sensor for detecting the position of a mechanical interaction, said sensor including:a first fabric layer having electrically conductive fibres machined therein to provide a first conductive outer layer allowing conduction in all directions along the layer; a second fabric layer having electrically conductive fibres machined therein to provide a second conductive outer layer allowing conduction in all directions along the layer; a central layer disposed between said first outer layer and said second layer, said central layer including conducting means; a first separate insulating layer disposed between said first conductive outer layer and said central layer; and a second separate insulating layer disposed between said second conductive outer layer and said central layer; wherein said conducting means provides a conductive path between said first conducting outer layer and said second conducting outer layer at the position of a mechanical interaction, and said position sensor has electrical connections to the first and second conductive outer layers only.
