Figure 9. (A) Flexible WSC array derived from air stable conductive polymer ink. (B) Schematic illustration for the fabrication of printed WSCs with a mask-assisted spray-coating method. (C) Integrated circuit of a WSC wristband that can successfully power a green LED bulb. (D) Air-stable conductive CP ink can be easily prepared through a facile assemble-disperse strategy, in which PANi and citric acid assemble into hydrogel in the assemble stage and sequentially disperse well in water to form CP ink in the disperse stage[115]. PET: Polyethylene terephthalate; CP: conductive polymer.
