Abstract Sodium alginate/graphene oxide (Al/GO) nanocomposite films were prepared by solvent casting. The structure, morphology, and electrical properties of Al/GO films were characterized by Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, and thermal analysis. The utilization of such an Al/GO film for a device that uses friction as the charging process to convert mechanical energy into electric power is reported. The triboelectric generator (TEG) was fabricated by stacking a drop‐cast Al/GO film bewteen indium–tin oxide (ITO)‐coated poly(ethylene terephthalate) (PET) and a PET sheet. Furthermore, the utilization of such a TEG as a pressure sensor is also illustrated.
