A two-dimensional position sensor comprising a substrate with a sensitive area defined by a pattern of electrodes including electrodes for determining x-position and electrodes for determining y-position. The x-electrodes and y-electrodes generally extend in the x-direction and are interleaved in the y-direction. The x-electrodes comprise at least first, second and third groups of elements shapedsuch that adjacent ones of the elements of the different x-electrode groups co-extend in the x-direction so that the x-electrodes provide ratiometric capacitive signals, thereby providing quasi-continuous x-position sensing across the sensitive area. In addition, the y-electrodes may be resistively connected or arranged in ratiometric pairs to provide quasi-continuous y-position sensing. Alternatively, the x-electrode groups may be interdigitated to form pairs of x-adjacent blocks of differing area to provide stepwise x-position sensing in combination with stepwise y-position sensing providedby the y-electrodes.
