A review on piezoelectric fibers and nanowires for energy harvesting

Abstract

Recent advances in self-powered electronic devices have urged the development of energy-harvesting technology. Batteries are gradually unable to satisfy the practical requirements for powering the different types of microelectronic devices owing to their drawbacks such as occupying a significant percentage and weight of portable products, the need to replace or recharge them, constructing an important environmental impact, and the probable seepage of electrolyte solutions. Various technologies for converting renewable energies into electricity have been reported. Particularly, energy harvesters based on piezoelectricity to convert mechanical energy into usable electricity have received considerable attention. Electrospun fibers from piezoelectric polymers and inorganic nanowires as emerging piezoelectric materials have shown great potential for energy-harvesting applications. This review paper summarizes energy-harvesting technology based on piezoelectric polymeric fibers, inorganic piezoelectric fibers, and inorganic nanowires. A comprehensive overview of fundamentals of piezoelectric effect, types of piezoelectric materials, energy harvesting from fibers, energy harvesting from inorganic nanowires, and energy harvesting from polymeric/inorganic fibers and nanowires composites are discussed.

A Review of Piezoelectric PVDF Film by Electrospinning and Its Applications

“…Among these, if we focus on the mechanical vibrations conversion into electrical energy, the devices based on piezoelectric properties have great potential [ 7 , 8 ]. So far, much research work has been devoted to the development and improvement of piezoelectric materials such as Pb(Zr,Ti)O 3 ceramics and Pb(Mg,Nb)O 3 -PbTiO 3 crystals, which can generate high piezoelectric output [ 1 , 9 , 10 , 11 , 12 ]. In addition to ceramics and crystals, polymer materials have started to gain attention recently due to their excellent mechanical flexibility, compatibility, and cheap cost.…”

A mini review on the generation of crimped ultrathin fibers via electrospinning: Materials, strategies, and applications

“…However, since the late 1990s until now, the consciousness in this technique has been growing, as evident from the increasing number of publications, due to its ability to form webs with unique properties (eg, high specific surface area, small fibers' diameter, flexibility, ease of functionality, excellent mechanical properties, good pore structures, extraordinary adjustability, low density, and so on). Therefore, it can be used in various areas such as tissue engineering, biomedical applications, sensors, antibacterial applications, catalysts, energy harvesting, self‐cleaning surfaces, food packaging, filtrations, and so on.…”

Direct generation of electrospun interconnected macroporous nanofibers using a water bath as a collector

“…Electrospinning is a technique for generating fibers with a diameter ranging from few nanometers to several micrometers [1,2]. Electrospun fibers can be formed in different morphologies resulting in their ability to be used in different applications such as oil cleanup, energy harvesting, biomedical applications, self-cleaning surfaces, keeping food fresh, and so on [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”
