Abstract
A stylus and sensor capable of determining levels of pressure applied to a tip are disclosed. The stylus has a tip configured to interact with and receive a force from a touch surface. The stylus includes a force sensitive resistor configured to vary resistance in an electrical circuit based on the force and a component for determining an amount of pressure corresponding to the force or a change in pressure based on the resistance in the electrical circuit. The stylus can have a chamber housing a slide-able plunger connected to the tip, the plunger being adapted to move in directions perpendicular or tangential to the surface when the force is applied. The resistor is disposed at an end of the chamber. The stylus can have a conductive strip on the resistor and a disc on the strip. The disc is configured to compress when force is applied by the plunger.
