Abstract:
1. A stylus comprising: a tip configured to receive a mechanical force when contacting a touch surface of a computing device, wherein the tip is configured to deform in response to receiving the mechanical force; a plunger connected to the tip and adapted to move in directions substantially perpendicular or tangential to the touch surface of the computing device in response to the tip receiving the mechanical force; a force sensitive resistor configured to vary resistance in an electrical circuit based on the force; a fastener attached to an end of the plunger distal from the tip and comprising an electrically conductive nut configured to removably secure the plunger and distribute the force received by the tip substantially evenly across the force sensitive resistor; and a component configured to determine an amount of pressure corresponding to the force or a change in an amount of pressure based on the resistance in the electrical circuit.
