Waterproof graphene electronic circuits

Water molecules distort the electrical resistance of graphene, but a team of researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact resistance is not impaired by humidity. This finding will help to develop new sensors -- the interface between circuits and the real world -- with a significant cost reduction.
