Abstract

A method of providing a variable resistance from a resistive member including a resistive resilient material comprises electrically coupling a first conductor with the resistive member at a first contact location over a first contact area; and electrically coupling a second conductor with the resistive member at a movable second contact location over a second contact area. The second contact location is movable relative to the resistive member to change the second contact location between the second conductor and the resistive member, the first contact location and the movable second contact location being spaced from one another by a distance. The method further comprises changing at least one of the first location, the second location, the first contact area, and the second contact area to produce a change in resistance in the resistive member, measured between the first conductor at the first contact location and the second conductor at the second contact location, as the resistive member deforms along the second conductor.
