<p>In the realm of flexible triboelectric nanogenerators (TENGs), the conversion efficiency of mechanical to electrical energy is paramount, yet the influence of piezoelectric ceramic polarization on TENGs' output remains inadequately studied. In this work, lead-free piezoelectric ceramics have been doped into polyvinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) and coupled with fluorinated ethylene propylene (FEP) to fabricate contact-separation type doped piezoelectric ceramic TENGs (PC-TENGs). A schematic illustrating the enhanced electrical output of TENGs by polarized ceramics is presented, with their theoretical underpinning substantiated through COMSOL simulations. The piezoelectric, ferroelectric, and dielectric properties of ceramics and composite films under various systems and states of polarization have been meticulously evaluated, alongside measurement of the surface charge density and other electrical attributes of the PC-TENGs across different frequencies, temperatures, and humidity levels. A chord diagram has been employed to synthesize the degree of correspondence and the correlation between all measured parameters and the enhancement of triboelectric performance, concluding that the doping of composite films with polarized ceramic powder is instrumental in the amplification of TENGs' electrical performance. This study not only charts a course for the refinement of TENG designs but also enriches the theoretical landscape governing their function.</p> Graphical abstract <p></p>
