Figure 4. (A) Schematic cross-sectional view of graphene coated, compressed, and encapsulated fabric (top) and a real sample after 10 washing cycles (bottom). (B) Finger joint motion detection, wrist joint detection, and elbow joint motion detection by compressed and encapsulated graphene textile^[72]. Flexible transparent micro-supercapacitor before electrolyte deposition^[81]. (B) A snapshot of the GO ink printing on a glass slide. (C) Assembled reduced graphene oxide (rGO) supercapacitor on flexible PET substrate^[82]. (D) Photograph of a 4 × 11 array of graphene MSCs printed on a flexible PET film. (E) Schematic circuit diagram (top) and optical image (bottom) of three devices in a series connection. (F) Galvanostatic charge-discharge (GCD) profiles for the three devices connected in series and parallel, respectively, in comparison with the GCD profiles for a single device. The GCD profiles were acquired at a current of 0.21 µA^[83].
