High-power energy harvesting and imperceptible pulse sensing through peapod-inspired hierarchically designed piezoelectric nanofibers

High-performance energy harvesting for human-sensing applications has been achieved through recent progress in piezoelectric-based wearable devices. Piezoelectric nanomaterials can be leveraged flexibility and biocompatibility while also enhancing piezoelectricity. However, such exhibit low piezoelectricity, limits the industrial-scale development of highly efficient piezoelectric Hence, design novel materials to significantly enhance piezoelectricity is necessitated. Herein, we demonstrate that a peapod-inspired which ZnSnO3 anchored on surface-modified carbon nanotubes (CNT) allows significant enhancement produced by poly(vinylidene fluoride-co-trifluoroethylene)-based (P(VDF-TrFE)-based) nanofibers (a material). The properties were exploited application as-prepared (NFs) flexible NFs energy-harvesting pulse-sensing systems, demonstrated high output power ((97.5 V 1.16 ?A) as well imperceptible pulse detection even posterior tibial arteries. This work provides scientific engineering framework delivering ZnSnO3-surface-modified CNT-P(VDF-TrFE) excellent performance use
