Abstract
Structures and methods are disclosed for an electronic device having an input surface that uses dual sensors to measure forces applied to the input surface. The forces can be estimated over a greater range of values than would be possible with either sensor alone. A second sensor can be used after a first sensor has reached a limit. A first sensor can be a strain sensor and a second sensor a pressure sensor. Both sensors may be resistance based, with signals from both sensors can be combined and measured by processing circuitry. Each sensor type may be part of planar arrays disposed beneath the input surface.
