Abstract
A location of a center of pressure is determined in two-dimensions by a multi-layer sensor, which has a first sensing layer with a first sensing area and a second sensing layer with a second sensing area. The first sensing area includes one or more first sensing cells, and the second sensing area includes one or more second sensing cells. The first and second sensing areas overlap in plan view. Each of the first and second sensing cells can be respectively defined by a set of linearly-varying sensing aperture patterns. In each of the first and second sensing cells, a combination of the respective set of linearly-varying sensing aperture patterns forms a uniform sensing aperture pattern. The location of the center of pressure can be determined using a maximum of four output signals from the multi-layer sensor.
