Abstract:
A variable resistance device comprises a resistive member having a resistive resilient material. A first conductor is configured to be electrically coupled with the resistive member at a first contact location over a first contact area. A second conductor is configured to be electrically coupled with the resistance member at a second contact location over a second contact area. The first contact location and second contact location are spaced from one another by a distance. The resistance between the first conductor at the first contact location and the second conductor at the second contact location is equal to the sum of a straight resistance component and a parallel path resistance component. At least one of the first location, the second location, the first contact area, and the second contact area is changed to produce a change in resistance between the first conductor and the second conductor.
