“…prepared semiconductive zinc oxide (ZnO) nanofibers via the sol–gel method combined with electrospinning and observed that the diameter of the precursor fibers increased with the increasing content of zinc acetate, while the size of the inorganic ZnO nanofibers decreased significantly with the increasing calcination time. Moreover, different ceramic nanofibers (aluminum oxide [Al 2 O 3 ], ZnO, copper oxide [CuO], titanium dioxide [TiO 2 ], titanium nitride [TiN], tin oxide [SnO 2 ], vanadium pentoxide [V 2 O 5 ], iron oxide [Fe 2 O 3 ], barium titanate [BaTiO 3 ], strontium titanate [SrTiO 3 ], and zirconium dioxide [ZrO 2 ]) have been successfully prepared and processed into well‐aligned nanofiber arrays 20,24–30 . To date, this method has been extended to many functional materials, for example, electrical, magnetic, ferroelectric, ferromagnetic, and structural machinery, particularly the anisotropic arrangement of active components to afford new properties for suitability in special applications.…”

One-dimensional sensing materials that are prepared via electrospinning and controlled annealing exhibit intrinsic properties, such as electron transmissivity, magnetic susceptibility, specific heat capacity, as well as optical and mechanical characteristics. Particularly, the electronic transmission characteristics of the ceramic fiber materials, such as the electrical conductivity, photocurrent, magnetoresistance, nanocontact resistance, and dielectric properties, exhibited great potential for applications in the next generation of electronic sensing devices.First, electrospun ceramic materials with different structural and functional characteristics were reviewed here, after which the strategies for improving their properties, as well as the method for assembling the flexible devices, are summarized. Moreover, the electrospun ceramic nanofibers were detailedly discussed regarding applications in device construction and wearable electronics, such as photosensors, gas sensors, mechanical sensors, and other energy storage devices.Finally, the future development direction of the electrospinning technology for multifunctional and wearable electronics skin was proposed.

One of the contributions of nanotechnology to our daily life is the preparation of a large variety of polymer-based nanofibers, which could be the basis of future wearable devices. Wearable electronics are a great part of smart textiles research. Herein, we have reported an easy method to fabricate electrically conductive cellulose nanofibers (CNFs). To fabricate CNFs, we first prepared cellulose acetate (CA) nanofibers by using the electrospinning technique and later, the deacetylation process was done to obtain the CNFs. The electroless deposition (ELD) technique was then used to create the conductive nanofibers. Copper (Cu) was used to coat the CNFs because of their high conductivity and low cost. The ELD process parameters including time, temperature, volume, and pH were optimized to obtain a nanofiber with higher conductivity. The optimized condition was temperature: 40 C, time: 10 min, volume: 600 ml, and pH: 13 to obtain a nanofiber web with 983.5 S/cm conductivity. Cu-coated CNFs were characterized by scanning electron microscope, energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, water contact angle, antibacterial activity, tensile, and electrical conductivity. The bending cycle test was performed to quantitatively demonstrate the durability and flexibility of the Cu-coated nanofibers. Cu-coated CNFs exhibited great performance to be used as a conductive layer with antibacterial activity.

To promote the energy density of symmetric all-solid-state supercapacitors (SCs), efforts have been dedicated to searching for high-performance electrode materials recently. In this paper, vanadium nitride (VN) nanofibers with mesoporous structure have been fabricated by a facile electrospinning method. Their crystal structures and morphology features were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The mesoporous structure of VN nanofibers, which can provide short electrolyte diffusion routes and conducting electron transport pathways, is beneficial to their performance as a supercapacitor electrode. Under a stable electrochemical window of 1.0 V, VN nanofibers possess an excellent mass specific capacitance of 110.8 F/g at a scan rate of 5 mV/s. Moreover, the VN nanofibers were further assembled into symmetric all-solid-state SCs, achieving a high energy density of 0.89 mW•h/cm 3 and a high power density of 0.016 W/cm 3 over an operating potential range from 0 to 1.0 V. These results demonstrate that VN nanofibers could be potentially used for energy storage devices.
