Flexible energy harvesters have become a research hotspot in both academia and industry because of their great advantages in powering wearable electronic devices. The flexible energy harvesters based on piezoelectric materials are recognized as a competitive method because of their sensitivity to mechanical deformation, excellent energy conversion performance, mature production technology and simple structure. This paper presents a comprehensive review to illustrate the research progress and future development of wearable flexible piezoelectric harvesters. In this work, the widely-used piezoelectric materials for flexible energy harvesters, including inorganic piezoelectric materials, organic piezoelectric materials and piezoelectric composites, are first summarized. The research progress on the influence of ceramic content, morphology, distribution, surface chemical modification, and the addition of conductive materials on the properties of piezoelectric composites are systematically discussed. Additionally, this paper also presents novel structures and fabrication methods of flexible piezoelectric energy harvesters. 1 Finally, future trends in research, development and innovation of flexible piezoelectric energy harvesters are outlined and prospected.

“…BaTiO3 is a typical ABO3 chalcogenide structure material [1], which has excellent ferroelectricity, piezoelectricity and plasticity properties. Because of its excellent performance, barium titanate is widely used in multilayer ceramic capacitors (MLCC), positive temperature coefficient (PTC) thermistors, sensors and other electronic components, and is known as the "pillar of the electronic ceramic industry" [2][3][4][5].With the rapid development of electronic technology, the requirements for electronic materials are getting higher and higher, especially for electronic components such as multilayer ceramic capacitors, integrated circuits, drivers and sensors, which are increasingly demanding. The miniaturization of electronic components, large energy storage capacity and the improvement of breakdown strength have become an imminent need and the future development trend of the electronics industry.…”

In this paper, erbium-doped barium titanate nanotubes with different concentrations were prepared by combining the anodic oxidation method with the low-temperature hydrothermal method. The TiO2 nanotubes produced by electrolysis using titanium flakes as substrate were put into barium hydroxide octahydrate solution for hydrothermal reaction, and different concentrations of Er-doped barium titanate nanotubes were prepared by adding different concentrations of Er(NO3)3·5H2O to the reaction solution. The samples with different doping concentrations were analyzed for their morphological structure, physical phase composition and ferroelectric properties. All samples were found to have complete barium titanate nanotube structure, and the diffraction peaks of XRD were compared with the standard Cope, and the doped samples were all tetragonal phase chalcogenide structure with no other impurities generated. From the hysteresis loop diagram of the samples measured by the TF-2000 ferroelectric analyzer, it can be found that the residual polarization intensity of the samples showed a characteristic of increasing and then decreasing with the increase of the doping concentration, and the residual polarization intensity was the largest at 0.151 uC/cm2 under the hydrothermal reaction condition of 180°C and 3 h with the Er3+ concentration of 0.0025 mol/L.

“…The crystallite size (≈53.2 nm) and particle size (305 nm) of the prepared BMT NPs are also less than other conventional methods. [ 16 ] Selvaraj et al prepared BT nanopowder using a low‐cost sol‐hydrothermal method. The results showed that the crystallite size increases with increases in temperature from 34 to 40 nm.…”

“…Recently, BT was prepared by using the solid-state reaction method but the particle size, purity of the raw material, and non-homogeneity degraded the dielectric properties of the material and also influence the product performance. [14,16] Therefore, seeking an alternative method to enhance their characteristic properties has provided the impetus to various researchers in the field of materials science. However, it is difficult to control their composition together with a complicated phase design.…”

Low‐temperature intercessions are the most proficient technique to control the particle size in the nanometres range with low agglomeration. Herein, BaTiO3 (BT) nanoparticles (NPs) are prepared at low temperatures by using the sol‐hydrothermal technique. An X‐ray diffraction (XRD) pattern of the powder signifies the pure tetragonal phase, and the average crystallite size (43.2 nm) is calculated using different methods: Scherrer's, uniform deformation model (UDM), uniform stress deformation model (USDM), and uniform deformation energy density model (UDEDM) analysis, and the structure is refined by Rietveld refinement method with a good fit value (χ2 = 1.66). Spherical and uniform surface morphology is counted up for BT NPs. Under suitable conditions, BT NPs can be prepared with an average particle size of ≈115 ± 10 nm. However, after sintering, the average grain size (335 ± 10 nm) of the BaTiO3 nanopowder is found to increase with dense grain boundaries. The dielectric behavior of the sample is analyzed with the variation of frequency at different temperatures. The effect of grain and grain boundary on the electrical properties of the material is also investigated by using complex impedance spectroscopy (CIS).
