Resistive Interpolation

Similar to one layer long slider, resistive interpolation can be used to design two-layer long sliders. To increase the length of sensor, extra segments are created using resistive dividers on the X lines. The segments can be designed such that they are both spatially as well as resistively interpolated.

Up to six extra segments can be added between channels to achieve the required sensor length. Resistive interpolation method can achieve a slider length of up to 300mm.
