Aka/also known as: strain gage

A strain gauge is a type of device used in force measurement whose electrical resistance changes when force (ie, strain) is applied to it and deforms a foil inside itself. These changes in resistance can be measured and translated into a force measurement. Standard IBM and Lenovo TrackPoint pointing sticks use several strain gauges mounted on the base of a tall, square stick to register the user's intent for cursor movement.
