Abstract Amid the global energy crisis and rising emphasis on sustainability, efficient harvesting has become a research priority. Nanogenerators excel in converting abundant mechanical thermal into electricity, offering promising path for sustainable solutions. Among various nanogenerator's materials, Polyvinylidene fluoride (PVDF), with its distinctive molecular structure, exhibits multifunctional electrical properties including dielectric, piezoelectric pyroelectric characteristics. These combined excellent flexibility make PVDF prime candidate material nanogenerators. In nanogenerators, this is capable of efficiently collecting energy. This paper discusses how PVDF's are manifested three types nanogenerators compares performance these addition, strategies to improve output demonstrated, physical chemical modification as well structural optimization such hybrid structures external circuits. It also introduces application natural human harvesting, prospects medical technologies smart home systems. The aim promote use self‐powered sensing, monitoring, thereby providing valuable insights designing more versatile

Flexible and wearable electronics often rely on piezoelectric materials, Poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) membranes are popular for this application. However, their electromechanical performance is limited due to a relatively low coefficient. To address this, study investigates the incorporation of zinc oxide (ZnO) nanorods (NRs) into P(VDF-TrFE) nanofiber membrane matrix. ZnO NRs were synthesized doped well-aligned nanofibers using electrospinning with high-speed rotating drum. The impact NRs’ mass fraction properties was evaluated. Results show that maximum coefficient (d33) −62.4 pC/N, 9.5 times higher than neat P(VDF-TrFE), achieved. These enhanced demonstrated excellent in finger-tapping bending detection, making them promising large-scale flexible sensor applications electronics. This approach offers simple effective route improve materials devices.
