    摘要： A sensor is provided, the sensor comprising a first layer (10) of padding material having an inner face and a second layer (12) of padding material having an inner face. The inner faces of the two layers face one another. The inner face of the first layer (10) is provided with a first printed conductive ink track (13) and the inner face of the second layer (12) is provided with a second printed conductive ink track (15). At least one of the printed tracks (13, 15) passes across the pad in a number of runs at a plurality of spaced locations. The first track (13) on the first layer (10) intersects at a plurality of locations with the second track (15) on the second layer (12). At least one of the layers (10, 12) is provided on its inner surface with a plurality of raised portions (12) arranged over the face of the layer (10, 12) between adjacent runs of the conductive track (13, 15) and facing the inner face of the other layer (12, 10) to maintain the two tracks (13, 15) apart when the sensor pad is unstressed, but which are compressible to deform to allow localised contact between the first and second tracks (13, 15) when pressure is applied to the pad.
