A force-sensing resistor is a device used in force measurement whose electrical resistance changes when a form of stress is applied. These changes in resistance can be measured and translated into a force measurement. The distinction between a force-sensing resistor and the similar-sounding strain gauge is that strain gauges have an underlying material that deforms, whereas force-sensing resistors do not. The Lexmark-Unicomp pointing stick makes use of force-sensing technology on a movable joystick-like implement to register the user's intent for cursor movement.
