When constructing sensors, remember your three variables:

  • Distance:¬†Resistance increases over distance no matter what the material
  • Pressure:¬†Some materials are pressure sensitive will decrease in resistance when pressure is applied to them.
  • Surface Area:¬†Increasing the size of the area for electricity to flow will decrease the resistance. For example, a foot of resistive thread in a line would be more resistive than a foot of the same thread that is stitched close together.
