“…It can be observed that the remnant polarization ( P r ) of the composites increases with increasing BaTiO 3 content, showing an enhanced piezoelectricity. The maximum remnant polarization of 0.294 μC/cm 2 has been achieved for the BT30 nanocomposite, as piezoelectric BaTiO 3 can promote the orientation of a large number of dipoles under the effect of an applied electric field . The area of the loop presents a tendency to increase with increasing BT content, suggesting an enhanced charge storage capability .…”

High-performance flexible piezoelectric polymer− ceramic composites are in high demand for increasing wearable energy-harvesting applications. In this work, a strategy combining solid-state shear milling (S 3 M) and fused filament fabrication (FFF) 3D-printing technology is proposed for the fabrication of high-performance biomimetic wearable piezoelectric poly-(vinylidene fluoride) (PVDF)/tetraphenylphosphonium chloride (TPPC)/barium titanate (BaTiO 3 ) nanocomposite energy harvesters with a biomimetic fish-scale-like metamaterial. The S 3 M technology could greatly improve the dispersion of BaTiO 3 submicrometer particles and the interfacial compatibility, resulting in better processability and piezoelectric performance of the nanocomposites. Typically, the FFF 3D printed energy harvester incorporating 30 wt % BaTiO 3 showed the highest piezoelectric outputs with an open-circuit voltage of 11.5 V and a short-circuit current of 220 nA. It could hence drive nine green LEDs to work normally. In addition, a 3D-printed biomimetic wearable energy harvester inspired by an environmentally adaptive fish-scale-like metamaterial was further fabricated. The fish-scale-like energy harvester could harvest energy through different deformation motions and successfully recharge a 4.7 μF capacitor by being mounted on a bicycle tire and the tire's rolling. This work not only provides a 3D printing strategy for designing diversified and complex geometric structures but also paves the way for further applications in flexible, wearable, self-powered electromechanical energy harvesters.

“…It is true that the manufacture of this device involves the use of nanomaterials such as nanowires, microparticles, and nanoflakes [36]. Similar to the dielectric energy storage devices [37][38][39][40][41], the synthetic crystal/ceramic components, such as barium titanate (BaTiO 3 ) [42], lead zirconate titanate (PZT) [43], Zinc sulphide (ZnS) [44], and ZnO [45,46] were proposed in many studies in the literature to improve the energy conversion efficiency and output performance [47]. The high surface-to-volume ratio, which is particularly prevalent in nanomaterial composites, has the tendency to produce specialized nanogenerator characteristics.…”

“…The doped indium oxide (ITO) exhibited high electrical conductivity and optical transmittance, but also has limited application due to the scarce and complicated preparation process. To solve these issues, the hybrid CPs with other conducting nanomaterials have been intensively proposed to avoid poor rigidity and bending resistance of traditional electrodes and improve the flexibility and conductivity [42,62,66,81,84,85]. These are promising methods for overcoming the differences in the local effective electric field in the nanocomposite, which results from the differences between the fillers and polymer phases in the electric field [65].…”

With the rapid growth of numerous portable electronics, it is critical to develop high-performance, lightweight, and environmentally sustainable energy generation and power supply systems. The flexible nanogenerators, including piezoelectric nanogenerators (PENG) and triboelectric nanogenerators (TENG), are currently viable candidates for combination with personal devices and wireless sensors to achieve sustained energy for long-term working circumstances due to their great mechanical qualities, superior environmental adaptability, and outstanding energy-harvesting performance. Conductive materials for electrode as the critical component in nanogenerators, have been intensively investigated to optimize their performance and avoid high-cost and time-consuming manufacture processing. Recently, because of their low cost, large-scale production, simple synthesis procedures, and controlled electrical conductivity, conducting polymers (CPs) have been utilized in a wide range of scientific domains. CPs have also become increasingly significant in nanogenerators. In this review, we summarize the recent advances on CP-based PENG and TENG for biomechanical energy harvesting. A thorough overview of recent advancements and development of CP-based nanogenerators with various configurations are presented and prospects of scientific and technological challenges from performance to potential applications are discussed.

Depletion of fossil fuels and increase in pollution through chemical batteries trigger the development of self‐powered devices based on flexible piezoelectric nanogenerators. Biocompatible piezoelectric PVDF nanocomposites merged with piezoelectric fillers like ZnO, KNN, and BaTiO3 reproduce amended piezoelectric current, contributing to the safe application as biosensors and flexible industrial devices. Optimized loading, precise selection, and variating the surface chemistry of piezoelectric filler, along with fabrication schemes comprising different structural configurations of composites, considerably influence its potential for application as energy harvester. Also, optimized processing condition upgrades dielectric constant, energy storage density, and reduces dielectric loss, thereby plummeting energy dissipation even after prolonged usage. Consequently, this paper reviews the principles, properties, fabrication techniques, and market application of PVDF composites. A detailed relationship of significant electrical properties of PVDF composites with its fabrication methods and piezoelectric parameters of fabricated PVDF composites with reported real‐life wearable, implantable, and industrial‐based portable piezoelectric devices are discussed in detail along with tabulated data for clear understanding of structure‐property relationship. Again, market strategy for establishing flexible PVDF composite as a piezoelectric nanogenerator has been discussed. An in‐depth knowledge is provided for procuring affordable futuristic large‐scale PVDF‐based nanogenerators exhibiting affordable market worth.This article is protected by copyright.
