Abstract

This project is about the study of effect of dimension on stretchable conductive ink electrical conductivity. The parameter use in this project is the different length, different width and different thickness. This paper presents the result on the different dimension effect on the electrical conductivity and the analysis of the microstructure surface. The ink was printed on the TPU substrate which is the substrate can be stretch. After print the ink on the TPU the stretchable conductive ink was cure in an oven at 120℃ with different time of curing, 15 minutes, 30 minutes and 45 minutes. The lower resistance for the length is 40 mm at 45 minutes curing time, the resistance is 1019.79 (R/sq). The result for the width is 7 mm at 45 minutes of curing time, the resistance is 679.86 (R/sq). The lower resistances for the thickness is 0.6 mm at 45 minutes of the curing time, the resistance is 566.55 (R/sq). The effect on the dimension that can be concluding the longer the length of the conductive ink, the higher the resistance it will give. For the thickness, the thicker the conductive ink, the lower the resistance it will show. Lastly, the wider the width of the conductive ink, the lower the resistance of the conductive ink. The curing time also effect the resistance of the conductive ink, the longer the curing time, the lower the resistance, this is due to the decreasing of the gap between the particles on the ink
