(A) Transparency of the electrode printed seven times with the picture in the inset [83]. Copyright 2015, AIP Publishing. (B) A general scheme for the fabrication of flexible electronic circuits on paper substrates by inkjet printing combined with ELD [91]. Copyright 2016, American Chemical Society. (C) Raw input image file for GNR images. (D) Thermal plasma GNR image inkjet printed on flexible FEP film. (E) Thermal image (temperature change extracted from baseline) recorded by an infrared camera when illuminated with NIR light on a printed thermal plasma image. (F) Enlarged thermal image in (E) and corresponding input image in (C). Dark spots in the input image appeared brighter in the thermal image because higher GNR densities led to larger temperature changes [92]. Copyright 2018, American Chemical Society. (G) The printed wire successfully illuminated the LED lamp, and at the same time, the whole circuit was subjected to bending. (H) The WiFi signal was restored after the smartphone was connected to the rGO antenna [94]. Copyright 2021, Royal Society of Chemistry.
