Abstract

The stretchable printed circuit are widely used days by days due to the physical characteristic that able to be bend and stretch. The stretchable printed circuit have been used in various field such as health, sport, industry and fashion. The research were done to find out the effect of ink thickness against the resistivity. Next, to find out the effect of temperature against the resistivity and the last one to find out the effect of strain applied against the resistivity. The samples were prepared with four different thicknesses (2, 4, 6 and 8 layers) where the layers was made using cellophane tape to create different thickness. The printing method used was screen printing method and the samples was measured using four point probe in the unit of Ω/sq. The samples were tested under three different condition where the first condition the sample will be measure under normal condition (room temperature – 32 ºC). The second condition, the sample were tested under various temperature (40, 60 and 100 ºC). The last condition the sample were tested in the room temperature under various strain applied (20, 40, 60 and 80 %), the Vernier caliper was used to apply the strain on the samples. Carbon was used as the conductive ink and thermal-polyurethane (TPU) was used as the substrate in this studies. The result of the study shows that when the ink thickness increase, the resistivity will decreased. As for the mechanical or strain test when the higher strain applied to the sample, the higher resistivity obtain by the sample.
