WVTR measurement. a Optical Ca-test set up utilized for the WVTR measurements. The inset shows a cross-section of the final device stack. b Overview of WVTR values in context of barrier film thickness for various application requirements.  The numbers next to square data points are from reported literature references, while star data points are for present study. The dashed line indicates the base value measured for comparative glass barriers fabricated in this investigation along with each batch of graphene-based barriers
