In the case of tungsten trioxide (WO<sub>3</sub>), doping with elements such as SnO<sub>2</sub> and SrO has garnered significant attention owing to its potential impact on structural, functional, and optical characteristics. We report on structural, functional, optical, and dielectric properties of SnO<sub>2</sub>/WO<sub>3</sub> and SrO/SnO<sub>2</sub>/WO<sub>3</sub> composites and, for comparison, WO<sub>3</sub> prepared via a wet chemical method. Crystallite phases were confirmed using x-ray diffraction patterns. Fourier-transform infrared spectroscopy and dielectric studies were employed to analyze the functional groups, dielectric constants, and losses of the SnO<sub>2</sub>/WO<sub>3</sub> and WO<sub>3</sub>/SnO<sub>2</sub>/SrO composites. Ultraviolet-visible spectroscopy and photoluminescence spectroscopy were used to examine the optical absorption and emission maxima, respectively. The energy bandgap was determined from the absorption spectra by using a Tauc plot. Additionally, all the prepared composites exhibited brighter and sharper narrow emissions in the photoluminescence spectra. Dielectric studies of WO<sub>3</sub>/SnO<sub>2</sub>/SrO composites revealed slightly better dielectric constants and lower dielectric losses than those of SnO<sub>2</sub>/WO<sub>3</sub> composites.

The high flexibility and significant ferroelectricity of poly(vinylidene fluoride) (PVDF) make them the most promising candidates for PENG applications among polymer piezoelectric materials. In the present work, NiO nanoparticles were incorporated in different ratios into a PVDF matrix, and their potential for use in piezoelectric nanogenerators was investigated. The PVDF/NiO (5 wt.%) nanocomposite PENG exhibited the highest electrical output, with a 2.8-fold increase in open-circuit voltage and short-circuit current observed as compared to a bare PVDF-based PENG. However, a further increase in the compositional ratio of NiO led to a decrease in PENG output. The improved piezoelectricity in the PVDF/NiO (5 wt.%) nanocomposite is attributed to the enhanced polar phases and improved ferroelectricity of PVDF. Further confirmation of the improved piezoresponse was explored by measurement of the piezoelectric coefficient (<i>d</i><sub>33</sub>) and dielectric study of the nanocomposites. The PENG electrical output was further simulated using the finite elemental method in COMSOL Multiphysics 5.5. The simulated results matched well with the experimental output, which confirmed the improved electrical performance of the PVDF/NiO nanocomposite-based PENGs. The enhanced performance of the nanocomposite PVDF film is attributed to the higher β phase in the PVDF. The efficiency of the PENG devices in motion-sensing applications was also explored.
