Robust magnetic energy harvesting with flexible lead-free poly(vinylidene fluoride)-Ba0.85Ca0.15Ti0.9Zr0.1O3 fibers and Metglas-based magnetoelectric composites

The article explores flexible materials merging BCZT–PVDF microfibers and Metglas for generating electricity from magnetic fields. They exhibit high MME voltage coefficient (472.1 V cm −1 Oe −1 ) and produce 14.8 V open-circuit voltage at 10 Oe AC, 50 Hz, translating to 4.7 µW cm −3 power density.
