Abstract: An apparatus and a method for force sensing, and an electronic device. The apparatus includes at least one first sensor, at least one second sensor, and a comparator. The at least one first sensor generates a first signal, the at least one second sensor generates a second signal, and the comparator receives both the first signal and the second signal. The first signal is determined by deformation of a deformable portion and temperature at the deformable portion, and the second signal is determined by the temperature at the deformable portion. The comparator determines whether the deformable portion deforms based on the first signal, the second signal, and the threshold signal, and further generates the third signal which is in the active state in response to the determination being positive. The apparatus can make an accurate response when the deformation of the deformable portion serves as an input operation.

Abstract: An apparatus for force sensing, and an electronic device. In the apparatus, a sensor generating a first signal includes a first hardware element attached to a deformable portion. The first signal depends on a first property of the first hardware element and a second property of a second hardware element. The first property has a dependency on deformation of the deformable portion, and a dependency m1 on temperature at the deformable portion in absence of the second hardware element. The second property has a dependency on the temperature at the deformable portion. When the temperature changes within a target range, the first change and the second change are induced into the first signal through the dependencies of the first property and the second property on the temperature, respectively, and the second change compensates for the first change. Such compensation renders the first signal robust to variations in the temperature.
