“…XPS spectrum data are analyzed in detail by Gaussian-Lorentz curve, and the splitting phenomenon of electron binding energies observed, which is compared with the symmetrical photoelectron peak of Ti element in pure BaTiO 3 [37,38]. This is because Ba and Ca atoms of BCZT share the A-site in ABO 3 , while Ti and Zr atoms share the B-site, causing their electronic binding energy to split [39]. All asymmetric 2p peaks of Ti split into two peaks, indicating that Ti 3?…”

The Mn-doped (Ba 0.85 Ca 0.15 )(Ti 0.9 Zr 0.1 ) 1-x Mn x O 3 (x = 0.000, 0.005, 0.010, 0.015, 0.100) (BCZTM) negative temperature coefficient (NTC) thermistor ceramics were prepared by solid-state method, and a research of their microstructures and electrical properties was also carried out. The excellent NTC properties of BCZTM ceramics sintered at high temperature were characterized by X-ray diffraction (XRD), scanning electron microscope, X-ray photoelectron spectroscopy, Raman spectroscopy, and infrared spectra (IR) analysis in this study. It is proved that the sintering temperature of BCZTM NTC thermistor ceramics is reduced by doping; it possesses a wide working temperature range (200-1100°C) as well. All XRD, Raman, and IR spectra indicate the formation of perovskite phase. A trace Mn-doping can regulate the resistivity and activation energy of materials, yielding B 400/900 = 9992.1-11186.8 K, q 900 = 245.9-664.4 X cm, E a600/900 = 0.9649-1.0175 eV, whereas excessive (x = 0.100) Mn-doping leads to a second phase. Besides, owing to small aging coefficient at 900°C (less than 0.8%) and good high temperature stability, it can be used as a candidate material for high temperature and harsh environment.

“…This strategy has been extensively adopted to fabricate flexible PENGs, especially for wearable energy harvesting. [487][488][489][490][491][492][493][494][495][496] As discussed in Section 3.3, there are three different combinations of piezoelectric composites depending on the piezoelectric properties of the filler or matrix. In the case of piezoelectric fillers and non-piezoelectric polymers, some flexibility can be obtained at the expense of the piezoelectric properties of inorganic piezoelectric fillers.…”

In today's digital age, the need and interest in personal and portable electronics shows a dramatic growth trend in daily life parallel to the developments in sensors technologies and the internet. Wearable electronics that can be attached to clothing, accessories, and the human body are one of the most promising subfields. The energy requirement for the devices considering the reduction in device sizes and the necessity of being flexible and light, the existing batteries are insufficient and nanogenerators have been recognized a suitable energy source in the last decade. The mechanical energy created by the daily activities of the human body is an accessible and natural energy source for nanogenerators. Fiber‐structured functional materials contribute to the increase in energy efficiency due to their effective surface to volume ratio while providing the necessary compatibility and comfort for the movements in daily life with its flexibility and lightness. Among the potential solutions, electrospinning stands out as a promising technique that can meet these requirements, allowing for simple, versatile, and continuous fabrication. Herein, wearable electronics and their future potential, electrospinning, and its place in energy applications are overviewed. Moreover, piezoelectric, triboelectric, and hybrid nanogenerators fabricated or associated with electrospun fibrous materials are presented.
