Patent ID: 8754662

Claim:
A capacitive sensor array, comprising: a large sensor electrode; and a plurality of small sensor electrodes, including a first small sensor electrode, a second small sensor electrode, and a third small sensor electrode, wherein the large sensor electrode and the plurality of small sensor electrodes are formed from a single layer of conductive material, wherein the first small sensor electrode is located on a same lateral side of the large sensor electrode as the second small sensor electrode, is consecutive with the second small sensor electrode in a spatial order that is along a direction of a longitudinal axis of the large sensor electrode and that includes any small sensor electrodes located at least partially between two interior points of the large sensor electrode, and is located on an opposite lateral side of the large sensor electrode from the third small sensor electrode, and wherein for each small sensor electrode of the plurality of small sensor electrodes, at least a portion of the small sensor electrode is located between two interior points of the large sensor electrode, and the longitudinal axis of the large sensor electrode intersects at least a portion of the small sensor electrode.
