Since the third scientific and technological revolution, electronic information technology has developed rapidly, and piezoelectric materials that can convert mechanical energy into electrical energy have become a research hotspot. Among them, piezoelectric polymers are widely used in various fields such as water treatment, biomedicine, and flexible sensors due to their good flexibility and weak toxicity. However, compared with ceramic piezoelectric materials, the piezoelectric properties of polymers are poor, so it is very important to improve the piezoelectric properties of polymers. Electrospinning technology can improve the piezoelectric properties of piezoelectric polymers by adjusting electrospinning parameters to control the piezoelectrically active phase transition of polymers. In addition, the prepared nanofibrous membrane is also a good substrate for supporting piezoelectric functional particles, which can also effectively improve the piezoelectric properties of polymers by doping particles. This paper reviews the piezoelectric properties of various electrospun piezoelectric polymer membranes, especially polyvinylidene fluoride (PVDF)-based electrospun nanofibrous membranes (NFs). Additionally, this paper introduces the various methods for increasing piezoelectric properties from the perspective of structure and species. Finally, the applications of NFs in the fields of biology, energy, and photocatalysis are discussed, and the future research directions and development are prospected.

“…In addition to solution casting, electrospinning, which combines electric poling and mechanical stretching, is another common method to prepare nanofiber membranes with larger piezoelectric coefficients and high energy conversion. , Note that the nanofiber films, when prepared via electrospinning, can also be directly used for energy harvesting without additional poling. Electrospinning can be done in two variations: far-field electrospinning (FFES) and near-field electrospinning (NFES).…”

Considering the limited supply of fossil fuel, pollution, problems with chemical batteries, and the many potential applications of wearable electronics, the development of more effective lightweight energy sources is important. Piezoelectric nanogenerators (PENGs) can convert a mechanical energy into an electric energy and sometimes may even have the potential to replace conventional chemical batteries. The combination of conventional textiles with PENGs leads to so-called "smart textiles", in other words, textile-based PENGs. More generally, textile-based PENGs can endow conventional textiles with special functionalities such as energy conversion and online health testing (using sensors), while the used conventional textiles can provide platforms for their deployment. This paper reviews the research progress of textile-based PENGs, discusses the classification of piezoelectric materials and electrode materials, and summarizes ways to improve their piezoelectric performance. In addition, several preparation methods of different device structures of textile-based PENGs are compared. Finally, the most important obstacles for the application of textile-based PENGs are addressed at the end of this paper. This compact but relatively comprehensive review will not only aid researchers to better understand textile-based PENGs but also attract the attention of related fields and perhaps inspire more exciting research and progress of wearable textile-based PENGs.

“…The force applied to a piezoelectric material (PZT) generates a voltage. These PZT materials are used as pressure or strain sensors as they can convert vibrations or applied pressure into electrical signals [87][88][89][90][91]. Fish gelatin nanofibers are made for flexible sensors using electrospinning technology.…”
