Abstract
A capacitive sensor array may include a first sensor element of a first plurality of sensor elements, and a second sensor element. The second sensor element may include a plurality of subelements, where each of the plurality of subelements is connected to at least another of the plurality of subelements by one of a plurality of connecting traces. A width of each of the connecting traces may be less than a width of any of the plurality of subelements. Connecting traces in a subset of the plurality of connecting traces may be staggered about a central axis of the second sensor element.
Claims20
A capacitive sensor array, comprising:
- a first sensor element of a first plurality of sensor elements;
- and
- a second sensor element comprising a plurality of subelements, wherein each of the plurality of subelements is connected to at least another of the plurality of subelements by one of a plurality of connecting traces, wherein a width of each of the connecting traces is less than a width of any of the plurality of subelements, and wherein connecting traces in a subset of the plurality of connecting traces are staggered about a central axis of the second sensor element.
A capacitive sensor array, comprising:
- a first sensor element of a first plurality of sensor elements;
- a second sensor element comprising a plurality of subelements, wherein each of the plurality of subelements is connected to at least another of the plurality of subelements by one of a plurality of connecting traces, wherein a width of each of the plurality of subelements is greater than a width of each of the plurality of connecting traces, wherein a first subset of connecting traces of the plurality of connecting traces is positioned on a first side of a longitudinal central axis of the second sensor element, and wherein a second subset of connecting traces of the plurality of connecting traces is positioned on a second side of the longitudinal central axis opposite the first side.
A capacitive sensor array, comprising:
- a first sensor element of a first plurality of sensor elements;
- and
- a second sensor element comprising a plurality of subelements connected together by a plurality of connecting traces, wherein each point in a unit cell associated with the first sensor element and the second sensor element is nearer to a gap between the first sensor element and the second sensor element than to a gap between any other pair of sensor elements, wherein the unit cell contains an equal number of subelements of the second sensor element on either side of a longitudinal central axis of the second sensor element, and wherein the second sensor element intersects the first sensor element at fewer than three intersections within a first unit cell associated with the first sensor element and the second sensor element.
