Background:
- Development of advanced materials for flexible and transparent electronic devices is crucial.
- Graphene and Poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) are promising materials for electronic applications.
- Existing nanogenerators often rely on less flexible or transparent materials.
Purpose of the Study:
- To demonstrate a flexible, transparent acoustic actuator and nanogenerator.
- To investigate the properties of graphene/P(VDF-TrFE)/graphene multilayer films.
