Lightweight hollow metallic spheres are attracting significant interest for nanogenerator applications due to their exceptional combination of low density and high mechanical strength. This balance structural integrity, reduced mass, specific strength is essential ensuring the durability long-term performance devices optimized efficient energy harvesting. In this work, we have fabricated lightweight high-performance Fe–Cr–Ni alloy sphere (HMS) based triboelectric nanogenerators (TENGs) as robust energy-harvesting devices. The HMS was by using a method involving sacrificial expanded polystyrene (EPS) metal slurry enhance properties conversion efficiency TENG device compared uncoated EPS device. Comprehensive characterization physical morphology, chemical composition, microstructural both conducted. electronic HMS, with work function 4.23 ± 0.2 eV, were found be superior those EPS, which exhibited 4.49 eV. difference, highlighted variances in potential observed surface Kelvin probe force microscopy (SKPFM) measurements, indicates higher electron transfer charge storage capabilities HMS. Furthermore, dielectric constant (κ) determined exceptionally high, measuring 1.6 × 107 at frequency 10 kHz reaching 3.7 2 MHz. These integral TENGs that incorporate flexible ITO-coated PET substrate, demonstrating remarkable capabilities. Notably, HMS-based exhibits an output 25 V even under minimal pressure, significantly outperforming EPS-based nanogenerator. findings confirm robust, solutions effective scavenging, suggesting substantial applicability current emerging technologies.
