High‐Efficiency Poly(Vinylidene Fluoride‐Co‐Hexafluoropropylene) Loaded 3D Marigold Flower‐Like Bismuth Tungstate Triboelectric Films for Mechanical Energy Harvesting and Sensing Applications

“…Therefore, Figure 6d shows the output sensitivity of the TENG, and these curves were generated with the impact of a ball falling from different heights. [67,72] The TENG (sensor) output increased almost linearly with the increase in height, and the obtained sensitivity was 0.88 V cm −1 . The real-time and practical application of the proposed TENG was demonstrated by using harvested mechanical energy available in daily life human body motions.…”

“…This reduction might be due to the aggregation of BWO marigold flower-like structures inside the PVDF-HFP polymer at higher weight concentrations. [34,62,67,68] Besides, the output electrical performance of the proposed TENG including effective power density and mechanical stability at various applied forces and frequencies was studied as shown in Figure 5c-e and Figure S3, Supporting Information. The effective output power density of the PVDF-HFP/2.5 wt% BWO CPF-based TENG was systematically analyzed by measuring its electrical output at various load resistances (R L ) ranging from 10 2 to 10 9 Ω.…”

Strategies Involved in Enhancing the Capacitive Energy Storage Characteristics of Poly(vinylidene fluoride) Based Flexible Composites

“…Among the several widely studied polymer-ceramic-based composites till date, it has been found that PVDF and its copolymers have gained numerous attention for the development of polymer-ceramic composite type energy storage device-based systems due to its several advantages. [80][81][82][83][84][85][86][87][88][89] First of all, PVDF and its co-polymers are perhaps the best known ferroelectric polymer which exhibits good piezoelectric properties too. [90][91][92][93] Its inherent ferroelectricity helps to improve its energy storage performance on one hand and on the other hand, its good piezoelectric performance enables this material to be applied as a mechanical energy harvester and sensor.…”

Aluminum impregnated zinc oxide engineered poly(vinylidene fluoride hexafluoropropylene)‐based flexible nanocomposite for efficient harvesting of mechanical energy

“…Therefore, it will be quite fascinating to explore the effect of Al@ZnO nanofiller on the physicochemical as well as body motion‐based energy harvesting properties of the nanocomposite. Here, PVDF‐HFP instead of PVDF has been utilized as a matrix owing to its higher electromechanical coupling factor and high piezoelectric strain coefficient along with good mechanical properties, cost‐effectiveness, chemical stability, weather resilient characteristics, and excellent film forming ability in comparison to the bare PVDF matrix 38 . Furthermore, external electrical poling is an important technique to enhance the NG output performance of the polymer‐nanocomposites.…”

The dipoles of the PVDF film were oriented along the field direction by the external electrical poling, which significantly enhances polarity, and leads to an increment of piezoelectricity.…”
