Figure S1. GO transferred over glass using a spatula.
Figure S2. Optical microscopy characterisation of the WPM. a) immediately after printing and b) 5 months after printing.
Figure S3. Evaluation of printing and resulting width of the WPM before and after transfer and GO transfer onto PET at different drying time.
Figure S4. Hydrophobicity of GO film over time filtered on nitrocellulose membrane.
Figure S5. WPM with wax height.
Figure S6. Adhesive peel-off wipe test. Inset: photo of conductive tracks after 5 peel-off counts.
Figure S7. Electronic circuit used for the LED switcher.
Figure S8. a) C1s spectra of GO and b) C1s spectra of rGO.
Figure S9. SEM characterization of a) GO and b) rGO.
The GO z-dimension (thickness) of the materials was ca. 1.0 to 1.2 nm. The maximum x-y dimensions were 554 nm. These data were provided by Angstrom Materials and are consistent with the SEM results (Figure S8).

2nd peel off 287.16 ±96.64
3rd peel off 310.54 ±107.76
4th peel off 312.81 ±115.89
5th peel off 326.75 ±129.43
