Direct Power Generation from a Graphene Oxide Film under Moisture

An efficient moisture–electric‐energy transformation is discovered by means of establishing an oxygen functional group gradient in a graphene oxide film. The moisture variation serves as an energy source to generate electric power with an energy‐conversion efficiency of up to ≈62%. Based on this fin...

Summary:An efficient moisture–electric‐energy transformation is discovered by means of establishing an oxygen functional group gradient in a graphene oxide film. The moisture variation serves as an energy source to generate electric power with an energy‐conversion efficiency of up to ≈62%. Based on this finding, a prototype power generator and a self‐powered respiratory monitor are demonstrated under the stimulus of the human breath.
