“…The result indicates that the values of discharged energy density depend on the remnant of polarization of the D-E hysteresis loop [92]. Our previous work has successfully enhanced the ferroelectric properties of P(VDF-TrFE) with higher remnant polarization and discharged energy density by incorporating 0.15 wt% of ZnO QDs [96]. It is assumed that ZnO QDs filled in the P(VDF-TrFE) matrix locally induce additional dipole moments.…”

“…Although ceramic fillers like BNT exhibit high pyroelectric properties as indicated in Table 3, it is essential to study quantum size effects like ZnO QDs on the electrical (ferroelectric, dielectric and pyroelectric) performance of energy harvesting and storage devices. Our previous work [96] shows that 0.15 wt% of ZnO QDs in P(VDF-TrFE) could contribute about half of the pyroelectric coefficient reported by [96] with a QDs size in the range of ~2.5 -3 nm. The interfacial polarization may arise from the interaction between the nanofiller and the polymer matrix during the poling process and contribute to the increase in the remnant polarization and pyroelectric coefficient achieved in this work.…”

“…It is assumed that ZnO QDs filled in the P(VDF-TrFE) matrix locally induce additional dipole moments. These local dipoles coupled with polymer dipoles are speculated to cause an increase in ferroelectricity [96]. Meanwhile, one-dimensional (1D) multiferroic BiFeO 3 and P(VDF-TrFE) exhibited a saturated hysteresis loop with the highest remnant polarization, P r = 9.7 mC/m 2 at 2 MV/m for BFO-50…”

“…Current research focuses on the inclusion of nanocrystals or quantum dots (QDs) into polymer matrix for various applications; perovskite quantum dots-embedded polydimethylsiloxane (PQDP) film-based triboelectric nanogenerator (TENG) on the bottom monocrystalline Si solar cell towards harvesting raindrop energy and solar energy [18], the composite P(VDF-TrFE) doped with CsPbBr 3 QDs for piezoelectric nanogenerators [19] and carbon dots (C-dots) in conducting polymers (polypyrrole (PPy) and polyaniline (PANI)) for energy storage applications [20]. Three main issues must be addressed for any polymer nanocomposite to be useful as an energy harvester as reported in our previous work [21]: the agglomeration of quantum dots (QDs), toxicity and energy harvesting performance. Surface modification using a capping agent is essential for controlling the as-synthesized QD size and preventing rapid agglomeration due to the high surface energy.…”

Advancements in nanotechnology and materials science have led to the development of a variety of nanogenerator materials with improved properties, making energy harvesting technologies increasingly viable for various applications, such as powering wearable devices, remote sensors, and even small electronic gadgets in the future. The evolution of hybrid materials consisting of polymers and nanoparticles as efficient energy harvesters and energy storage devices is in high demand nowadays. Most investigations on organic ferroelectric P(VDF-TrFE) as a polymer host of polymer nanocomposite devices were primally focused on the β phase due to its excellent electrical properties for various application purposes. Nanofiller is also introduced into the polymer host to produce a polymer nanocomposite with enhanced properties. A brief description of various physical quantities related to ferroelectric, dielectric, pyroelectric effects and Thermally Stimulated Current (TSC) for energy harvesting applications in nanogenerator materials is presented. This article explores the different materials and uses of various nanogenerators. It explains the basics of the pyroelectric effect and the structure of pyroelectric nanogenerators (PNGs), as well as recent advancements in micro/nanoscale devices. Additionally, it discusses how the performance of ferroelectric, dielectric, pyroelectric, and TSC are impacted by the annealing treatment of P(VDF-TrFE) polymer.

“…Hence, the process was carried out in two steps-500 rpm for 10 s and 2000 rpm for 40 s-to obtain a 20 μm thick film.Subsequently, the device underwent annealing. Temperature greatly influences crystallinity, while the optimal range lies between the Curie temperature (120 °C) and melting temperature (150 °C)[37,38]. Moreover, the paraelectric phase allows for a better crystallinity ratio (up to 91%), and higher crystallinity results in enhanced remnant polarization.…”

Wireless implantable devices (WIDs) have the potential to revolutionize biomedical sensing, but their power supplies face significant challenges. Traditional energy transfer methods such as inductive and RF have limitations due to associated tissue losses. This work demonstrates a promising approach to this problem, using a flexible implantable ultrasound energy harvester (IUEH) made of biocompatible Poly (vinylidene fluoride-co-trifluoro ethylene) (P(VDF-TrFe)) free-standing film. Unlike commonly used piezoceramic devices, IUEH can be fabricated using economical solution processing methods such as spin coating. In addition, the PVDF-TrFE Ultrasound energy harvesters are rarely reported in the literature. The device performance of the polymer IUEH was investigated in air, water, and animal meat tissue, and the results show that it can generate a power output of 1.1 mW/cm2 in meat, and 1.4 mW/cm2 in water at 80 kHz. The device fabricated using a free-standing piezoelectric thin film, offers an optimum output that is comparable to other P(VDF-TrFe) based high-frequency devices. Additionally, its flexible design, lower costs, and biocompatibility make it a promising alternative to lead-based devices; thus, offering safety, affordability, and quick customization, while promoting minimally invasive procedures and driving innovation in medical device development.

Polymer‐based pyroelectric thin films are crucial functional materials at the core of flexible and lightweight electronic devices, such as wearable monitoring sensors, energy harvesters, and infrared detectors. Nevertheless, the pyroelectric properties of the polymer films, such as poly(vinylidene fluoride‐trifluoroethylene) (P(VDF‐TrFE)), vanish when the surrounding temperature exceeds the ferroelectric‐to‐paraelectric transition temperature, and thus limits their pyroelectric performance to a low‐temperature range. Herein, to mitigate this issue by employing a new class of P(VDF‐TrFE) copolymer which has a low TrFE molar content is proposed. Fine‐tuning of the structure through thermal annealing in a vacuum environment significantly favors robust and highly polarized polymer films with a large area. Electric poling combined with an optimal annealing temperature (110–120 °C) gives highly ordered ferroelectric crystalline domains in the polymer films. Consequently, this remarkably broadens the temperature range (roughly up to 140 °C) for which the polymer film still presents high pyroelectric properties (pyroelectric coefficient 50 µC (m2K)−1). This study provides an alternative choice for pyroelectric polymer films with enhanced pyroelectricity in applications that require wider temperature ranges.
