Novel flexible nanogenerators

In this paper, three kinds of flexible nanogenerators are introduced, the first one is electrostatic nanogenerator using graphene oxide film, the second one is nanogenerator made of ZnO nanoparticles and multi-wall carbon nanotube with polydimethylsiloxane, the third one is piezoelectric nanogenerator based on a new type piezoelectric material 0.9525(K_0.5Na_0.5NbO₃)-0.0475LiTaO₃ (KNN-LTS) nanopowder. These three nanogenerators can be used to harvest energy. Furthermore, these kinds of nanogenerators have some advantages, such as the simple process of fabrication and good flexibility.
