“…The dielectric properties of BaTiO 3 -NH 2 /LDPE nanocomposite have also been studied 16 and PAM/BaTiO 3 nanocomposite 17 has been prepared as an intelligent soft substance. Polymer/BaTiO 3 nanocomposites have been prepared by many methods such as spin coating, 18 electrospinning, 19 and solution casting methods. 20 Ionizing radiation as well as ionizing particles can alter the physical as well as the chemical structure of the exposed material.…”

Polyacrylamide (PAM) was used as a matrix material for preparing nanocomposite samples filled with different weight fractions (1, 3, 5, 7, and 15%) of barium titanate (BaTiO3) by casting method. The PAM/7% BaTiO3 has been irradiated with gamma radiation at a dose of 200 Gy in order to investigate its impact on the structure as well as its optical and dielectric properties. The results show that the BaTiO3 nanoparticles are well incorporated inside the PAM matrix and the crystallite size of BaTiO3 has been decreased upon filling inside the PAM matrix as confirmed by the analysis of Fourier transform spectroscopy, and X-ray diffraction patterns, respectively. The prepared films show direct forbidden optical transition. Moreover, filling PAM with 7% BaTiO nanoparticles has increased the dielectric permittivity from 1.07 to 2.44 (at 100 kHz) with a slight increase in the loss factor from 0.015 to 0.020. In the other side, gamma radiation has decreased the crystallite size in relative to the un-irradiated sample with increased dielectric permittivity (2.89) and a slight decrease in the loss factor (0.019) at 100 kHz.

“…The highest output voltage of piezoelectric nanogenerators (PENGs) made of PVDF nanofibers was 360 mV, whereas PENGs made of PVDF/BaTiO 3 nanocomposites with a 6% w/w concentration of BaTiO 3 had a peak output voltage of 740 mV. 60 In another study, the piezoelectric capabilities of electrospun PVDF/BaTiO 3 nanocomposites were enhanced by the addition of 5, 10, and 20 wt% of BaTiO 3 NPs. β-Phase content could reach 91.0% for PVDF/10 wt% BaTiO 3 with a maximum output voltage of 50 V during repetitive bending and releasing at 4 Hz and about 4 V under the frequency of 2 Hz and the pressure of 0.2 N. 55 It must also be pointed out that KNN, which has the same perovskite structure as BaTiO 3 , has also attracted considerable attention.…”

“…To track the faint vibration of a loudspeaker, a flexible PVDF/BaTiO 3 pressure sensor with a sensitivity of 18.0 V N −1 was developed. 60 By attaching the sensor to a stereo, the maximum periodic output voltages of 150 mV and 500 mV could be obtained when the music was played at different sound pressure levels of 60 dB and 80 dB. It was even feasible to discern between different genres of popular music ( Fig.…”

With the rapid development of the economy and technology, intelligent wearable devices have gradually entered public life. Flexible sensors, as the main component of wearable devices, have been widely concerned. However, traditional flexible sensors need an external power supply, lacking flexibility and sustainable power supply. In this study, structured poly(vinylidene fluoride) (PVDF)-based composite nanofiber membranes doped with different mass fractions of MXene and zinc oxide (ZnO) were prepared by electrospinning and were then assembled to flexible self-powered friction piezoelectric sensors. The addition of MXene and ZnO endowed PVDF nanofiber membranes with better piezoelectric properties. The structured PVDF/MXene-PVDF/ZnO (PM/PZ) nanofiber membranes with a double-layer structure, interpenetrating structure, or core–shell structure could further enhance the piezoelectric properties of PVDF-based nanofiber membranes through the synergistic effects of filler doping and structural design. In particular, the output voltage of the self-powered friction piezoelectric sensor made of a core–shell PM/PZ nanofiber membrane showed a good linear relationship with the applied pressure and could produce a good piezoelectric response to the bending deformation caused by human motion.
