After coming to the conclusion that copper tape was more conductive than aluminum film, we discovered that using the copper tape on thin plastic yielded better results than the copper tape on paper because the plastic is more durable than paper. We continued experimenting and through trial and error, we realized that X shaped cuts work better with the copper tape than H shaped cuts.
We also observed that the wires on resistors are thinner than the standard pin and so resistors are more likely to loose contact with the conductive material. Our solution was to use a ‘weaving’ method which works better for resistors as Long as the isolation boxes are wide enough.
Using the X-cuts and the weaving method we were able to successfully produce a touch sensor demo.
