“…Pyroelectric nanogenerators (PyENGs) use the variation in spontaneous polarization inside pyroelectric materials to transform heat energy into electric energy. This is generated by oscillations of electric dipoles caused by a change in time-dependent temperature [ 91 , 92 ]. The creation of electric current through materials having a non-center symmetrical crystalline structure when subjected to a time-dependent temperature gradient is referred to as the pyroelectric effect [ 93 , 94 ].…”

Natural sources of green energy include sunshine, water, biomass, geothermal heat, and wind. These energies are alternate forms of electrical energy that do not rely on fossil fuels. Green energy is environmentally benign, as it avoids the generation of greenhouse gases and pollutants. Various systems and equipment have been utilized to gather natural energy. However, most technologies need a huge amount of infrastructure and expensive equipment in order to power electronic gadgets, smart sensors, and wearable devices. Nanogenerators have recently emerged as an alternative technique for collecting energy from both natural and artificial sources, with significant benefits such as light weight, low-cost production, simple operation, easy signal processing, and low-cost materials. These nanogenerators might power electronic components and wearable devices used in a variety of applications such as telecommunications, the medical sector, the military and automotive industries, and internet of things (IoT) devices. We describe new research on the performance of nanogenerators employing several green energy acquisition processes such as piezoelectric, electromagnetic, thermoelectric, and triboelectric. Furthermore, the materials, applications, challenges, and future prospects of several nanogenerators are discussed.

In this study, a novel and sustainable triboelectric material is successfully designed and developed by extracting keratin from recycled fur and combining it with chitosan to create a keratin/chitosan triboelectric nanogenerator (CK‐TENG) device. The device is designed for the simultaneous treatment of waste and the generation of green and clean energy, crucial for addressing global challenges. CK is prepared through a freeze‐drying method to overcome the weak mechanical properties of keratin and achieve a high surface contact area, which is important for triboelectric properties. The results showed that the output voltage is improved by 375% compared to the TENG without keratin, with values reaching 322 V under a 6 N. It produced a high power density of 14.4 W m−2 and excellent cyclic stability for more than 8000 cycles, which are crucial for practical applications. Further, the potential applications are also studied, and the results showed that it can turn on over 250 light‐emitting diodes (LEDs), display liquid crystal display (LCD), and charge capacitors under 6 N. Moreover, it is successful in harvesting energy from waste vibrations, acoustic energy, and as a shoe, and the electrical output is utilized to power electronic devices. Furthermore, the power density harvested by the device is higher than that of TENG devices made with keratin‐rich materials. Therefore, this study paves the way for the use of keratin‐based bio‐waste materials for clean and green energy production, which can play significant roles in applications such as the charging of electronic devices, biomedicine, sensors, and smart textiles.

Technological developments and innovations in the wearable device field have created huge consumer demand. Hence, designing energy harvesting devices are of utmost importance. Of the various types of energy harvesting devices, triboelectric nanogenerators (TENGs) have come to the fore, as it can efficiently harvest electrical energy from mechanical motions. To date, polymers and metals have dominated the triboelectric series, but there is a need to develop novel composite materials and 2D materials to enhance the performance of TENGs. In this study, electrospun polyacrylonitrile nanofibers are prepared and decorated with zeolitic imidazole framework‐67 (ZIF‐67@PAN) to form pearl‐necklace‐like fibers. ZIF‐67@PAN nanofibers are prepared by immersing PAN nanofibers for different hours (1, 5, 10, and 24 h) in ZIF‐67 solution, they provide more roughness, and efficient surface contact area. The immersion of PAN fibers in ZIF solution for longer times increases overall energy harvesting efficiency. Different amounts of MXene are deposited on PVDF; the inclusion of MXene improves the charge transfer properties of TENGs. PAN@ZIF‐67 is used as a positive tribolayer and PVDF@MXene as a negative tribolayer. The optimized TENG device has 305 V, 10.6 µA, and 10.9 W/m2 power and demonstrated promising energy harvesting characteristics and self‐powered sensing efficiency.
