and poly (sodium 4-styrenesulfonate)(PSS)-intercalated GO composite films used as the
humidity-responsive dielectrics. A hydrophilic and electrically-insulating PSS polymer was
used as an intercalant between the individual GO platelets to enhance the water permeation
characteristics. Capacitive-type humidity sensors fabricated by forming metal electrodes on
both sides of the GO and GO-PSS films were installed into the charge pumping system …
