Abstract:
1. A two-dimensional capacitive sensor device comprising: a first sensor electrode having a varying width along a first direction, a maximum width at a first edge along said first direction, and a minimum width at a second edge along said first direction; a second sensor electrode having a varying width along said first direction and substantially identical widths at said first edge and at said second edge; a third sensor electrode having a varying width along said first direction, a minimum width at said first edge, and a maximum width at said second edge; wherein said first sensor electrode, said second sensor electrode, and said third sensor electrode are arranged in a first sensor cell; wherein said second sensor electrode is disposed between said first sensor electrode and said third sensor electrode in the arrangement of said first sensor cell; wherein said first sensor electrode, said second sensor electrode, and said third sensor electrode have substantially equal surface area; and wherein said two-dimensional capacitive sensor device comprises a plurality of sensor cells disposed in a repeated fashion in a single layer.
