“…Electrospinning is widely established as a simple, economical, and versatile technology for fabricating triboelectric nanogenerators (TENGs) [117], sensors [118][119][120], piezoelectric nanogenerators (PENGs) [121,122], and photoelectric scanners (PESs) driven by magnetic force [112,[123][124][125][126][127]. Over recent years, electrospun fiber geometries have been used to develop different kinds of PVDF structures, such as rods, tubes, particles, and flakes [128,129].…”

Owing to their biocompatibility, chemical stability, film-forming ability, cost-effectiveness, and excellent electroactive properties, poly(vinylidene fluoride) (PVDF) and PVDF-based polymers are widely used in sensors, actuators, energy harvesters, etc. In this review, the recent research progress on the PVDF phase structures and identification of different phases is outlined. Several approaches for obtaining the electroactive phase of PVDF and preparing PVDF-based nanocomposites are described. Furthermore, the potential applications of these materials in wearable sensors and human energy harvesters are discussed. Finally, some challenges and perspectives for improving the properties and boosting the applications of these materials are presented.

“…The electricity output is dependent on the electroactive phase and crystallinity of PVDF, PVDF is a semicrystalline polymer with four major phases: α, β, γ and δ. 24 The β phase in all trans planar zigzag conformation (TTTT) has been extensively explored, and it is the most favorable in piezoelectric nature among all phases due to its unique chain conformation in the crystal unit cell and provision of the largest residual polarization. 25,26 The piezoelectric effect is a workable technique that might be incorporated into textiles to generate electricity on the human body.…”

Because batteries' ability to power portable and wireless devices is limited, a great deal of research has been conducted on energy harvesting technology as a self‐power source for portable devices. Harvesting mechanical energy from human motion is an attractive approach to obtaining green and renewable energy by converting wasted ambient energy to electrical power. Hence, integrating an energy harvester into shoes is among the most interesting possibilities for harvesting energy from the body. In this paper, we explore the effect of flexible substrate mechanical parameters on the energy harvesting capability of a flexible piezoelectric film. Analytical modeling and simulations of a smart structure composed by polyvinylidene fluoride film stuck on three different textiles substrates have been done to evaluate the ability of this approach to harvest energy and its application within shoes to transform mechanical energy generated by the foot while walking into electrical energy. The maximum harvested power of the polyvinylidene difluoride film under 200 N compressive force was found to be 5.37 μW on a Cotton textile, which is a potentially useful amount of energy.

Lightweight, polyacrylonitrile‐derived electrodes with different additives were fabricated using high‐throughput nozzle‐free electrospinning. The electrospun precursor nanofibers (PNFs) containing iron oxide, gold nanoparticles, or reduced graphene oxide (rGO) were subjected to oxidative stabilization and carbonization to obtain a carbon‐rich conductive nanofiber structure. Scanning electron microscopy showed that the carbon nanofibers contracted between 11 and 55% while the Fourier‐transform infrared spectroscopy confirmed that the carbon nanofibers were thermally stable. Thermogravimetric and differential scanning calorimetry results revealed that the cross‐linking of the chain molecules and cyclization were completed. Next, cyclic voltammetry results indicated that the electroactivity of the modified screen‐printed carbon electrodes was decreased by 85% due to the presence of carbon glue. The modified device presented significant enhanced electrochemical responses with the inclusions of nanoparticles, with rGO showing a 2.13 times higher electroactive surface area, followed by iron oxide (two times) and gold nanoparticles (1.37 times) than the equivalent PNFs.
