Abstract: A force sensor for detecting a force on a surface of a device. The force sensor may include a force-receiving layer and a substrate disposed below the force-receiving layer. A first force-sensitive component may be disposed on a surface of the substrate, and a second force-sensitive component may be disposed proximate to the first force-sensitive component. In some embodiments, sensor circuitry may be operatively coupled to the first and second force-sensitive components, and configured to compare a relative electrical response between the first force-sensitive component and the second force-sensitive component to compute a force estimate. The force estimate may compensate for a variation in response based on the location of the components relative to a location of the force.
