“…The reduction of power at non-optimal load resistance is more flat than that in our previous study, indicating that the TENG could accommodate more sorts of loads. In general, compared with other wave-driven TENGs, this study has achieved a new benchmark in power density [23,29,30,[41][42][43][44].…”

Marine distributed devices are essential infrastructure for exploring and utilizing the ocean. As the most common carrier of these devices, floating and submerged buoys are subject to a bottleneck of power supply. Recent progress in nanogenerators could convert the high-entropy marine kinetic energy (e.g., wave) robustly, which may form an in-situ power solution to marine distributed devices. This study is devoted to develop a stackable triboelectric nanogenerator (S-TENG), while each layer of it is made into multiple channels carrying PTFE balls in between Aluminum electrodes. In the experiments based on forced motion, the peak power density of the S-TENG reaches 49 W/m3, about 29% promotion from our previous benchmark. The S-TENG has also become less vulnerable to directional variation of the excitation, making its integration on various platforms more flexible in real conditions. In practice, the S-TENG has demonstrated its capability of powering LEDs as well as various sensors measuring salinity, temperature and acidity, which means the S-TENG could self-power many compact marine buoys.

“…Triboelectric nanogenerators (TENGs) may gather green energy from irregular surroundings at low frequencies by connecting contact electrification with electrostatic induction. Blue energy, for example, may be extracted from ocean wave motion, which is fundamentally random and travels at low frequencies (near to 1 Hz) [ 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ]. The benefits of triboelectric nanogenerators are their small weight, low cost, simple operation principle, and lack of sophisticated production [ 61 , 62 , 63 , 64 ].…”

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.

“…Plants can provide valuable inspiration for both macrostructures and nanostructures that enhance physical and chemical TENG properties, [189] and they are also an excellent source of novel biodegradable materials. The studies described in this section have drawn inspiration from flowers, [223,224] lotus leaves, [225][226][227] cocklebur seeds, [228] wheat, [229][230][231] wood, [215,232,233] and sugarcane [234] to enhance TENG devices with abilities such as increased harvesting range and sweat repulsion. Herein, we will first describe TENGs that utilize plant-inspired macrostructures and nanostructures, then those that use widely available plantderived materials in an effort to combat plastic waste.…”

Triboelectric nanogenerators (TENGs) have quickly become one of the most popular mechanisms for harvesting ambient mechanical energy due to their simple design, facile construction, abundance of material choices, and cost‐effectiveness. Over the past decade, TENG research has been heavily focused on methods of construction that improve output or function in specific applications. Recently many researchers have looked to the design of the world around them to create more advanced TENGs, investigating the unique qualities that organisms use to survive and thrive in their environments. These bioinspired TENGs are often more efficient, more environmentally friendly, or possess more capabilities than their standard TENG counterparts. Herein, this paper provides a review of recent advances in TENGs that utilize inspiration or novel materials from nature for use in biomonitoring, artificial intelligence texture detection, wind energy harvesting, blue energy harvesting and other applications. The unique qualities of these TENGs include sweat‐resistance, biodegradability, increased output parameters, and more. This review is organized into plant‐inspired, animal‐inspired, human‐inspired, and other bioinspired TENGs. Each study's source of inspiration, the problems they sought to address, and the output parameters of the device are discussed, followed by a discussion of current challenges and promising future directions for field advancement.
