Abstract
A self-shielding capacitive sensor array may include a first plurality of sensor elements and a second plurality of sensor elements, where each of the second plurality of sensor elements intersects each of the first plurality of sensor elements, such that each of the first plurality of sensor elements may be capacitively coupled with each of the second plurality of sensor elements. The first plurality of sensor elements may be configured to shield each of the second plurality of sensor elements from a noise source.
