Abstract

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 is demonstrated and it is shown to be excellent for close proximity sensing without touching it. This method opens up a novel avenue for future human-machine interaction applications.
