“…In an era increasingly dominated by small electronic devices and sensors, the focus has intensified on creating compact, efficient energy-harvesting technologies. Unlike traditional large-scale power generators, modern energy harvesters are characterized by their compactness and adaptability, which enables them to be integrated into various environments and serve as localized, continuous power sources. − Furthermore, energy harvesters have recently been used for biomonitoring applications − and artificial intelligence-assisted sensors. , Among the renewable energy sources, wind energy, which is renowned for its abundance and sustainability, has traditionally been harnessed by using large wind turbines located in open areas. Despite their effective power generation, these turbines face limitations due to the need for high wind speeds, substantial land space, and environmental impacts, including noise pollution and aesthetic concerns.…”

Triboelectric nanogenerators (TENGs) stand out in the evolving landscape of wind-energy harvesting because of their potential for sustainable energy production. Despite these advancements, challenges remain in achieving practical designs that integrate seamlessly into everyday environments. Our study introduces a vertical blind-shaped triboelectric nanogenerator (VB-TENG) inspired by common vertical blinds in residential settings. The VB-TENG harnesses wind energy through an innovative design involving thin, vertically aligned poly(ethylene terephthalate) films, each coated with aluminum. This design serves not only as a functional energy harvester but also as a harmonious addition to urban aesthetics, mimicking the appearance and movement of traditional blinds. Utilizing vortex-induced vibration, the VB-TENG efficiently converts wind energy into electricity, a process validated through simulation and high-speed camera analyses. Our extensive experiments demonstrate that the effectiveness of the VB-TENG is considerably influenced by structural elements such as the number, width, and thickness of the films, attached lead weights, and varying wind conditions. Furthermore, the capability of our harvester extends beyond energy harvesting to function as a self-powered wind sensor, showcasing its multifunctionality. The VB-TENG offers a unique combination of efficiency, aesthetic integration, and multifunctionality. This marks a significant step forward in wind-driven TENG technology by proposing an energy-harvesting solution that is effective and elegantly integrated into the fabric of daily living environments, paving the way for more sustainable and practical energy solutions.

The instability of the ocean waves, such as intermittence, randomness, and irregularity, greatly affects the application of a triboelectric nanogenerator (TENG) in its aspects and leads to the irregularity and uncontrollability of its output performance. Hence, the energy storage TENG (ES-TENG) based on the ratchet mechanism is proposed in this work. The ES-TENG uses the ratchet mechanism to store the wave energy in the clockwork spring and then releases it in a centralized way to convert the wave energy into electric energy. When the ES-TENG adopts this method, the change of external excitation does not affect its output performance. Simultaneously, the shell of the ES-TENG is duck-shaped, which can better adapt to the wave environment. The peak power, open-circuit voltage, and short-circuit current of the ES-TENG are 6.2 mW, 495 V, and 19 μA, respectively. In the simulated wave experiment, the ES-TENG can successfully drive a temperature sensor. In summary, this work shows an economic, environmental friendly TENG that can adapt to the wave motion, and its output performance is not affected by wave instability, which has an important guiding significance for the further development and utilization of TENG in ocean energy.
