Abstract Flexibility, higher piezoelectric performance, and long‐lasting stability of devices have a great demand in next generation energy technologies. Polyvinylidene fluoride (PVDF) polymer has greater mechanical flexibility, but it suffers from low performance. Herein, sandwich‐structured film (SS‐PF) is designed by inserting the conductive poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) layer between two PVDF layers. The SS‐PF based flexible harvester (f‐PEH) generates voltage current 3.73 times 4.64 than pristine type f‐PEH. Moreover, f‐PEH shows no degradation output confirming excellent over 6 months.

Piezoelectric materials, due to their ability generate an electric charge in response mechanical deformation, are becoming increasingly attractive the engineering of bone and neural tissues. This manuscript reports effects addition nanohydroxyapatite (nHA), introduction gold nanoparticles (AuNPs) via sonochemical coating, collector rotation speed on formation electroactive phases biological properties electrospun nanofiber scaffolds consisting poly(vinylidene fluoride) (PVDF). FTIR, WAXS, DSC, SEM results indicate that nHA increases content fiber alignment. The rotational not only alignment but also PVDF PVDF/nHA fibers. Increased orientation each additives resulted increased SFE water uptake. In vitro tests conducted MG-63 hiPSC-NSC cells showed adhesion cell proliferation. PVDF-based composites with AuNPs promising candidates for development advanced tissue applications, combining electrical functionality activity support regeneration.
