“…This phenomenon is mainly caused by the gradual reduction in dipolar orientation polarization in response to the applied electrical field. [ 52,53 ] The dipoles failed to align in the direction of the applied electrical field at higher frequencies, while they have plenty of time for the alignment at lower frequencies. Furthermore, as shown in Figure 4b, all the nanocomposites have a low tan δ value comparable to that of the pure PVDF, which be attributed to the influence of the incorporated BTO nanoparticles on the dielectric relaxation behavior of the polymer matrix.…”

The improvement of wearable electronics is making energy harvesters appealing, as they lessen the requirement for regular recharge of wearable gadgets. In this work, fully printed, flexible piezoelectric nanogenerators (PENGs) with excellent performance are created using a 3D printing technology. This fully-printing method is based on triethoxyvinylsilane (TEVS) coated barium titanate (BTO) nanoparticles, polyvinylidene fluoride-co-trifluoroethylene (PVDF-TrFE), and silver electrode for additive manufacturing. The organic vinyl silane (VS) functional groups, which form a strong bond between inorganic nanoparticles and polymer, contribute to the homogeneous dispersion of BTO nanoparticles in the matrix. Consquently, these fully printed VS-BTO/PVDF-TrFE PENGs outperform their untreated counterpart in terms of output voltage and power density, with a higher output voltage of 54 V even after 13 500 cycles and a higher power density of 28.5 μW cm −2 . In practice, as-printed devices may actively adapt to human movement and detect the pulse from multipoint mechanical activity identification. The fully printed PENGs developed in this work show excellent potential to be used in wearable electronics for a new generation of sensing applications.

“…Utilizing the piezoelectric properties and semiconductor coupling effect of ZnO nanowires (ZnONWs), Professor Zhonglin Wang's research group successfully converted mechanical energy into electrical energy and developed the world's smallest generator, a piezoelectric nanogenerator, for the first time. [14][15][16][17] In 2012, polyethylene terephthalate (PET) and PI films with different friction characteristics were assembled into the first friction-type nanogenerator, which effectively improved the electromechanical conversion efficiency and electrical output of the device, 14 and the relevant research reports have attracted wide attention from researchers in many areas. 15,17,18 Similar to the field of flexible displays, the current mainstream is flexible organic light-emitting diode (OLED) technology, among which activematrix organic light-emitting diode (AMOLED) displays have become one of the hottest research directions in the field of consumer electronics in the last decade.…”

“…Yagi and Tatemoto [ 14 ] introduced the trifluoroethylene (TrFE) into the PVDF molecular chain to form a PVDF copolymer PVDF‐TrFE. Sahoo et al [ 15 ] reported that Ca‐doped ZnO nanofillers enhance the dielectric properties of PVDF‐TrFE composite films. For a composite film with a coercive field of 41 MV/m., the saturation polarization value was 1.32 μC/cm 2 and the residual polarization value was 0.604 μC/cm 2 .…”

MWCNT@PDA/PVDF-TrFE and MWCNT@PDA/PVDF-TrFE-CTFE composite films with high dielectric constant, low dielectric loss and excellent energy storage density were prepared by solution casting method. The best component of composite film (2.0 wt% MWCNT@PDA/PVDF-TrFE-CTFE, named C) was selected as the middle layer of the sandwich structure, and the upper and lower layers were made up by pure PVDF-TrFE film (named A) and pure PVDF-TrFE-CTFE films (named B). By testing and comparing the microstructure and performance of the single-layer composite film and the sandwich structure composite film, the influence of the matrix and structure on the performance of the composite film was discussed. The results showed that the dispersion effect of the filler in the matrix became worse, the dielectric constant gradually increased, the dielectric loss of the composite film did not change significantly, and the energy storage density first increased and then decreased with the increasing of the filler content. At a frequency of 10 3 Hz, the dielectric constants of 2.0 wt% MWCNT@PDA/PVDF-TrFE and 2.0 wt% MWCNT@PDA/PVDF-TrFE-CTFE composite films were 9.00 and 13.88, which were 1.9 and 2.9 times of pure films. When the electric field was 1100 kV/cm, the energy storage density of composite film BCB was 6.36 times of film C.
