Abstract
Embodiments described herein provide capacitive sensor arrays. The capacitive sensor arrays include a plurality of column sensor elements arranged in a plurality of columns and a plurality of row sensor elements arranged in a plurality of rows. The plurality of rows and the plurality of columns are arranged such that each of the row sensor elements is at least partially within a gap between adjacent ones of the column sensor elements. A capacitance between a first portion of one of the columns and an adjacent first portion of one of the rows is greater than a capacitance between a second portion of one of the columns and an adjacent second portion of one of the rows.
