Piezoelectric nanogenerators (PENGs) based on electrospun membranes hold significant promise for applications in wearable electronics, biomedicine, and multifunction sensors. The evolution of composite fiber can effectively address the challenges low output power poor stability PENGs. Herein, a structured polyaniline-coated halloysite nanotube (PANi@HNT) was synthesized through oxidative polymerization. These nanomaterials were dispersed within poly(vinylidene fluoride) (PVDF) due to high conductivity polyaniline surface charge they carry. Consequently, agglomeration fibers during electrospinning mitigated, resulting significantly reduced dielectric loss improved piezoelectric properties membranes. Notably, PENGs incorporating 15% PANi@HNT achieved an impressive voltage 90 V demonstrated stable performance over 10,000 cycles, with peak density reaching maximum 116.42 μW/cm2. Such show human movement monitoring as well energy harvesting, storage, utilization. Specifically, generated from induce regular flickering light strip consisting 0.2 W beads continuous illumination board comprising 0.05 red LEDs. Moreover, brief PENG is capable driving electronic watch.
