To meet future demands for sustainable and environmentally friendly technology, many research groups are focusing on triboelectric nanogenerators (TENGs), which can scavenge and convert the available mechanical energy into electrical energy. Researchers are working to comprehend the influence of triboelectric material surfaces as well as the properties that play an important role in determining the overall output performance of TENGs. The selection of tribonegative and tribopositive materials based on the charge in triboseries and different processes for manufacturing the triboactive material and its surface modification play important roles in attaining optimal TENG performance. The most significant tribonegative material is polyvinylidene fluoride (PVDF), and its electroactive polar β-crystalline phase is responsible for higher TENG performance. However, PVDF has some intrinsic limitations such as lower electrical conductivity and dipole moment and nonpolar α-crystalline phase at room temperature. Interestingly, these are the main factors that determine the output performance of TENG applications in energy harvesting and wearable sensors. In this review, we have mainly focused on the influence of varying processing methods like solution casting, 3-D printing, spin coating, and electrospinning on the output performance of PVDF-based TENGs. The effect of nanoscale materials on the PVDF crystalline phase is also studied in detail. Additionally, an extensive analysis of recent advancements in health monitoring, wearable sensors, and energy harvesting applications of PVDF-based TENGs is included.

“…Therefore, PVDF nanofiber mats are suitable TN layers for developing the TENGs. 12,18 To generate PVDF nanofiber mats, electrospinning is one of the easiest methods. In the electrospinning technique, a high voltage is often applied to the viscous polymer solution to generate nanofiber mats.…”

“…TENGs mainly function through the coupling mechanism of tribo-electrification and electrostatic induction between the tribo-negative (TN) and tribo-positive (TP) materials. 12 Various TENG structural arrangements have been well fabricated, and its functioning mechanisms are entrenched in four fundamental modes relying on the frictional interaction formed between the (TP) and (TN) materials, viz., vertical contact separation (CS), 13 lateral sliding (LS), 14 single electrode (SE), 15 and freestanding (FS) electrode mode. 16 For poly(vinylidene fluoride) (PVDF)based TENGs, the vertical CS working mode is suitable choice due to its ease of fabrication.…”

Triboelectric nanogenerators (TENGs) are renowned for capturing large-scale unused energy from ambient surroundings. A sustainable TENG can meet future energy demands without contaminating our environment. In the present study, we have synthesized nickel oxide nanoparticles (NiO NPs) via the coprecipitation method. Further, NiO NPs were doped with poly(vinylidene fluoride) (PVDF) (0 to 9 wt % w.r.t. PVDF concentration) to prepare the PVDF-NiO electrospun nanofibrous mat. The output efficiency was calculated in terms of open-circuit voltage (V oc ) and short-circuit current (I sc ). NiO-doped PVDF and thermoplastic polyurethane (TPU)-based TENG generated enhanced performance compared to the pristine PVDF (P-Ni-0)/TPU-based TENG. Among the six combinations of samples fabricated, 7 wt % of NiO-doped PVDF (P-Ni-7)/TPU-based TENG generated the utmost voltage of 252 V, which is almost 22-fold higher than the P-Ni-0/TPU triboelectric pair generated voltage (11.5 V). Similarly, the maximum current achieved was 7.3 μA, which is almost a 9-fold enhancement over the P-Ni-0/TPU triboelectric pair (0.8 μA). The power density of the optimized TENG ((P-Ni-7)/TPU) was 0.86 mW/m 2 , and it was directly used to light up 15 LEDs. Furthermore, a flexible and self-powered P-Ni-7/ TPU-based TENG device was demonstrated for real-time biomechanical motion measurements. Overall, this work disclosed a facile technique for doping NiO NPs into a PVDF matrix, and the fabricated TENG demonstrated efficiency when used for mechanical energy harvesting and sustainable power-supplying systems for miniaturized wearable electronic devices.

“…Furthermore, the preparation method of high quality and large area TENG lms has also attracted researchers' attention as well. Under normal circumstances, semiconductor layers of TENG are usually fabricated through blade technique [43], dipping method [44], spin-coating [41], rolling method [45] et.al, and the polymer layers are usually purchased or synthesized by phase inversion method [43] and so on.

Low-cost, handily prepared, and efficient large-scale triboelectric nanogenerator (TENG) is considered as the new scheme for distributed mechanical conversion or renewable blue energy utilization. Semiconductors with high carrier mobility introduction potency overcome pure polymer restriction for uncompetitive short current density. An extremely popular all-inorganic lead-free double perovskite Cs2AgBiBr6 (CABB) has emerged as extraordinary potential material in the substitution of semiconductor triboelectric material, which overcomes the limitations of high impedance associated with organic polymer insulator-based materials. In this current study, assembled by CABB which was certified as an available positive frictional material, TENG with a sandwiched structure of ITO/c-TiO2 (compact TiO2)/m-TiO2 (mesoporous TiO2)/CABB - the poly tetra fluoroethylene (PTFE)/Al exhibits appropriate performance on environmental stability and output capacity. A comparison of the fabrication process showed that spraying is an inexpensive method to prepare large-scale functional films of CABB TENG with brilliant relative dielectric constant and work function (Wf) difference that possess more distinguished output characteristics. This was confirmed by the appearance of higher open-circuit voltage of 105 V, larger short-current density of 2.45 mA/m2 at 0.25 Hz motion parameter, and more abundant power density output of 0.76 W/m2 under a higher frequency of 10 Hz. Further study clearly confirmed that both higher frequency and larger contact area are conducive to the total output power, while terminal charging speed is inversely or positively proportional with capacitance or mechanical frequency. The final physical display effect showed that spraying with CABB TENG could light up at least 53 commercial yellow LEDs, holding decent energy conversion ability. This confirms its efficiency, high throughput, and cost efficiency.
