Force Sensing Linear Potentiometer (FSLP)

Integration Guide

Like the basic single-zone FSR, the Interlink Electronics FSLP has an FSR ink layer and a

conductor substrate layer separated by an adhesive spacer. The FSLP’s conductor layer

however, is not simply a set of interdigitated silver fingers; it consists of two drive lines connected

to either end of a printed fixed resistor and a sense line. Silver fingers orthogonally protrude along

the entire length of the fixed resistor. These silver fingers are interdigitated with the sense line.

When the FSR ink and conductor membranes are pressed together, the sense line is shorted to a

point along the fixed resistor through the orthogonally protruding fingers. The resistance from

either drive line to the touch point is proportional to the location of the touch along the length of

the fixed resistor.
