“…Hence it is recommended that the optimum number of layers to be printed should be determined. 66 In this work, based on the results mentioned by Abu-Khalaf et al , 66 we considered printing three layers. In addition to the inkjet printer parameters, the post-processing treatment such as sintering, which involves the merging of the particles, plays an important role in determining the conductivity of the printed electronic circuit of the wearable device.…”
