Flexible polymer-based piezoelectric nanogenerators (PENGs) have gained significant interest due to their ability deliver clean and sustainable energy for self-powered electronics wearable devices. Recently, the incorporation of fillers into ferroelectric polymer matrix has been used improve relatively low properties PENGs. In this study, we investigated effect various nanofillers such as titania (TiO2), zinc oxide (ZnO), reduced graphene (rGO), lead zirconate titanate (PZT) on PENG performance nanocomposite thin films containing in poly(vinylidene fluoride-co-trifluoro ethylene) (P(VDF-TrFE)) matrix. The were prepared by depositing molecularly P(VDF-TrFE) nanofiller nanoparticles (NPs) spread at air/water interface onto indium tin oxide-coated polyethylene terephthalate (ITO-PET) substrate, they characterized measuring microstructures, crystallinity, β-phase contents, coefficients (d33) using SEM, FT-IR, XRD, quasi-static meter, respectively. Multiple PENGs incorporating within developed assembling film-coated substrates a sandwich-like structure. Their properties, open-circuit output voltage (VOC) short-circuit current (ISC), analyzed. As result, 4 wt% PZT, which was named P-PZT-4, showed best VOC 68.5 V with d33 value 78.2 pC/N content 97%. order maximum values PZT (68.5 V) > rGO (64.0 ZnO (50.9 TiO2 (48.1 V). When optimum integrated simple circuit comprising rectifiers capacitor, it demonstrated an excellent two-dimensional power density 20.6 μW/cm2 storage capacity 531.4 μJ 3 min. This optimized type found be superior when compared those literature. film shows potential application source low-powered
