Abstract
A functional layer for a moisture electric generating battery cell wherein the functional layer includes graphene oxide having a ratio of C═O bonds to C—C bonds of more than 1:9. The functional layer include treated graphene oxide having an interlayer spacing that is greater than the interlayer spacing of graphene oxide from which the treated graphene oxide is prepared. The functional layer consists of graphene oxide and a polymer binder that is selected to bond with an electrically conductive substrate. The polymer binder may be one or more of: PVA, PVB, PMMA or PVP. The graphene oxide and polymer binder are treated with acid such as HCl, H2SO4 or HNO3. The electrically conductive substrate forming an electrode may be mounted onto a further substrate, for use as a moist-electric generation (MEG) in an electronic device. The electronic device is configured to have a surface positioned in contact with the skin of a subject when in use.
