Abstract
A position sensor comprises first and second electrodes that generally extend in a first direction and are arranged in a pattern that defines a sensitive area, the second electrodes interleaved with the first electrodes in a second direction. The first electrodes comprise first, second, and third groups of elements, elements in the first, second, and third groups being connected to each other but not to elements in another group. The elements have shapes configured for adjacent elements in the first and second groups to co-extend in the first direction over a first portion of the sensitive area and to provide ratiometric capacitive signals with respect to each other in the first direction, and adjacent elements in the second and third groups to co-extend in the first direction over a second portion of the sensitive area and to provide ratiometric capacitive signals with respect to each other in the first direction.
