Abstract
A sensor is provided. The sensor includes a planar sensing area including a sensor layout. The sensor layout includes an interior portion, an edge portion, and edges. The sensor layout also includes interior sensing elements, the interior sensing elements being located in the interior portion, and edge sensing elements, the edge sensing elements being located in the edge portion. The interior sensing elements are arranged in the sensor layout such that the interior sensing elements generally do not extend beyond a predetermined distance from the edges. Moreover, the edge sensing elements are arranged to extend beyond the predetermined distance and interlace with the interior sensing elements in the interior portion. The sensor further includes a controller and a connector, the connector coupling the planar sensing area to the controller.
