Abstract
Systems and methods related to piezoelectric based force sensing in touch devices are presented. One embodiment, for example, may take the form of an apparatus including a touch device having a deformable device stack and a piezoelectric element positioned relative to the deformable device stack such that the piezoelectric element deforms with the deformable stack. Deformation of the piezoelectric element generates a signal having a magnitude discernable as representative of an amount of force applied to the touch device.
