Reduced graphene oxide ultrathin films are fabricated by a reproducible exfoliation method at the liquid/air interface, and they show high transparency, tunable sheet resistance, uniform electric conductivity, and structural homogeneity over a large area. A flexible relative humidity sensing matrix...
