Abstract
A capacitive sense array configured to improve noise immunity in detecting a presence of a conductive object is described. In one embodiment, a capacitive sense array includes at least a first set of sense elements disposed in straight parallel lines along a first axis of the capacitive sense array. A second set of sense elements is disposed in crooked paths about a second axis of the capacitive sense array. The first and second sets form a capacitive sense array that includes crooked sense paths in at least one of the axes of the sense array.
