Abstract

There is now a new technology that is well developed, which has the potential to conduct electricity through the use of ink utility. This technology is called conductive ink and has recently been launched with the introduction of various materials. In most cases, the conductive ink formulation uses materials such as silver, carbon and other conductive materials as a filler. There is also a substance that is still fresh in the carbon black conductive ink industry. Carbon black is a modern treasure dubbed “wonder material” with outstanding electricity conduction properties. In ink formulation, the use of carbon black as a conductive material can offer many advantages, but certain factors affect carbon black’s efficiency during the conduction of electricity. One of the variables is carbon black’s properties and behaviors, which may influence the threshold of the ink and its percolation. Such variables are a new thing that is still being explored by researchers, as the use of carbon black is still new in conductive ink technology. Based on the existing formulation of conductive ink, which is carbon black as a filler, a study on the effect of free vibration energy on conductive ink has been conducted. Four different forms have been patterned into ink samples, which are a straight line, zigzag, curve, and square pattern. Their separate widths are printed out for each pattern, which is 1 mm, 2 mm, and 3 mm. Three experiments will be performed in this research to achieve the targets, which are sheet resistivity test using a four-point probe, hardness test using nanoindentation with the effect with and without vibration, and studies using a scanning electron microscope on the presence of fatigue or crack. Based on this research, it can be concluded that the curve is a better pattern followed by the straight line, whereas vice versa with zigzag, and 1 mm samples are less effective in conducting electricity compared to 3 mm samples based on distance. In the future, the results of this study will be used to improve the efficiency of carbon in conductive ink technology.
