Piezoelectric polymer textiles offer distinct advantages in the fabrication of wearable nanogenerators (NGs). One effective strategy to enhance output capacity NGs is modulate piezoelectric performance textiles. This paper focuses on further improving properties nylon-11,11 through post-drawing and annealing treatments. We elucidate evolution morphology ferroelectric phase submicron/nanoscale fibers during post processing as well corresponding changes performance. The drawing process primarily enhances orientation crystalline reduces fiber diameter, while more effectively promotes crystal size crystallinity. Afterward, we propose an optimal postdrawing assisted-electrostatic spinning process. Under synergistic effects these post-treatments, remanent polarization (Pr) textile increased 4.7 times that untreated textile, resulting amplified outputs. voltage, current, power density prepared PENG reached 21.5 V, 800 nA, 1.88 mW·m-2 (80 MΩ), respectively. Notably, at pressures exceeding 8 kPa, mechano-voltage current sensitivity high 266 mV/kPa 13.99 nA/kPa, respectively, which extraordinary compared other comparable nylon-based triboelectric NGs. Furthermore, investigated potential application biomechanical energy harvesting human movement monitoring. Experiments demonstrated its effectiveness powering light bulbs, tracking walking status, monitoring finger/hand/wrist gestures.

Abstract Piezocomposites provide lightweight, flexible and scalable technologies for efficiently converting mechanical energy into electrical energy. For sustainable production, we examined a low‐cost, biobased alternative to convert piezoelectric Hydroxyapatite (HA) having particle size of 53.26 nm made from chicken eggshell waste was combined with polyurethane (PU) produce composites. In situ polymerization performed using aliphatic isocyanates, isophorone diisocyanate, poly(propylene glycol) 1,4‐butanediol. The properties six different composite films varying HA concentrations (0–25%) were optimized statistical mixture design approach. Fourier transform infrared spectroscopy, thermogravimetric analysis, X‐ray diffraction dynamic analysis scanning electron microscopy utilized physicochemical characterization. As the concentration increased, enhanced, as uniform dispersion observed within PU matrix. An oscilloscope displayed an output voltage 17.46 V at 16 Hz, 3 N force applied 25% film. dielectric constant, loss resistivity are frequency functions, impedance showed low‐frequency values high properties. present study has indicated that PU/HA biocomposites cost‐effective lightweight can be used in devices biomedical wearable electronics. © 2025 Society Chemical Industry.
