Abstract
In one embodiment, an active stylus includes one or more computer-readable non-transitory storage media embodying logic for wirelessly communicating with a device through a touch sensor of the device. The active stylus also includes a tip configured to receive an applied force and a force sensor configured to receive an inverse transferred force from a force-transfer element. The force-transfer element is mechanically coupled to the tip and configured to apply the inverse transferred force to the force sensor. The inverse transferred force is inversely correlated with the applied force when the applied force is less than a threshold force.
