Abstract

A capacitive touch sensor (100) comprises a row array of conductive strips (22) and a column array of conductive strips (24) arranged in a grid with a plurality of junction areas (28) formed therebetween, wherein at least one of the row or column conductive strips includes at least one electrically isolated region (235) positioned between two contiguous junction areas of the plurality of junction areas formed by the grid.
