Abstract
A position sensor is arranged to detect the position of a mechanical interaction, such as the application of manual pressure. A first fabric layer has electrically conductive fibers machined therein to provide a first conductive outer layer allowing conduction in all directions along the layer. A second fabric layer has electrically conductive fibers machined therein to provide a second conductive outer layer allowing conduction in all directions along the layer. A central layer is disposed between the first outer layer and the second outer layer. The central layer includes conductive elements. A first insulating separating element is disposed between the first conductive outer layer and the conducting elements. A second insulating separating element is disposed between the second conductive outer layer and the conducting elements. The conducting elements provide a conductive path between the first conducting outer layer and the second conducting outer layer at the position of a mechanical interaction.
