Water waves in wild sea have unique characteristics of being huge, random, irregular, and of low frequency. To effectively harvest such vibrational energy, any devices should be light enough to float, sensitive even to small amplitudes, durable against harsh environmental conditions, easily replaceable after long-term use, and easily linked to form a network. Here, a floating buoy-based triboelectric nanogenerator (FB-TENG) is demonstrated to effectively harvest the vibrational energy with full satisfaction of these requirements. The FB-TENG consisted simply of a power generation unit, which was packed in an acrylic case, and a height-adjustable support, which was attached to a floating buoy. Even for the small amplitude of water waves, the height-adjustable support provides vigorous vibration at the power generation unit; which was sufficient to power 30 light-emitting diodes (LEDs), and operate a digital thermo-hygrometer and an anenometer. Under saltwater (salinity of 40%), thermal shocks (temperature range of 4–60 °C), and strong ultraviolet irradiation (power of 10 W), the FB-TENG generates stable electric power by virtue of the acrylic packing of the power generation units. The FB-TENG also generates electric power from the various and mixed amplitudes and frequencies of water waves coming from all directions. Furthermore, the FB-TENG can easily be integrated into a network for high-power generation. This work provides a significant step forward in the harvesting of the blue energy of water waves, and the realization of self-powered sea mark and weather monitoring systems in wild sea.

基于浮标的摩擦电纳米发电机,可有效收集野生海中不规则和随机水波产生的振动能量
野生海中的水波具有巨大,随机,不规则和低频的独特特征。为了有效地收集这种振动能量,任何设备都应轻到足以漂浮,甚至对小振幅也敏感,在恶劣的环境条件下具有耐用性,在长期使用后易于更换,并且易于连接形成网络。在这里,基于浮标的摩擦电纳米发电机(FB-TENG)被证明可以有效地收集振动能量,并完全满足这些要求。FB-TENG仅仅由一个装在丙烯酸盒中的发电装置和一个高度可调的支架组成,该支架固定在浮标上。即使是小幅度的水波,可调节高度的支架也可以在发电装置上提供剧烈的振动。足以为30个发光二极管(LED)供电,并可以操作数字温湿度计和风速计。在盐水(盐度为40%),热冲击(温度范围为4–60°C)和强紫外线(功率为10 W)的情况下,FB-TENG依靠电源的丙烯酸填充物来产生稳定的电源代单位。FB-TENG还从来自各个方向的水波的各种混合振幅和频率中产生电力。此外,FB-TENG可以轻松集成到网络中以产生高功率。这项工作为捕集水波的蓝色能量,实现野生海域自供电的海标和天气监测系统迈出了重要的一步。并操作数字温湿度计和风速计。在盐水(盐度为40%),热冲击(温度范围为4–60°C)和强紫外线(功率为10 W)的情况下,FB-TENG依靠电源的丙烯酸填充物来产生稳定的电源代单位。FB-TENG还从来自各个方向的水波的各种混合振幅和频率中产生电力。此外,FB-TENG可以轻松集成到网络中以产生高功率。这项工作为捕集水波的蓝色能量,实现野生海域自供电的海标和天气监测系统迈出了重要的一步。并操作数字温湿度计和风速计。在盐水(盐度为40%),热冲击(温度范围为4–60°C)和强烈的紫外线辐射(功率为10 W)下,FB-TENG依靠电源的丙烯酸填充物来产生稳定的电源。代单位。FB-TENG还从来自各个方向的水波的各种混合振幅和频率中产生电力。此外,FB-TENG可以轻松集成到网络中以产生高功率。这项工作为捕集水浪的蓝色能量,实现野生海域的自供电海标和天气监测系统迈出了重要的一步。FB-TENG具有较强的紫外线照射能力(功率为10 W),通过发电单元的丙烯酸包装,可产生稳定的电力。FB-TENG还从来自各个方向的水波的各种混合振幅和频率中产生电力。此外,FB-TENG可以轻松集成到网络中以产生高功率。这项工作为捕集水波的蓝色能量,实现野生海域自供电的海标和天气监测系统迈出了重要的一步。FB-TENG具有较强的紫外线照射能力(功率为10 W),通过发电单元的丙烯酸包装,可产生稳定的电力。FB-TENG还从来自各个方向的水波的各种混合振幅和频率中产生电力。此外,FB-TENG可以轻松集成到网络中以产生高功率。这项工作为捕集水浪的蓝色能量,实现野生海域的自供电海标和天气监测系统迈出了重要的一步。FB-TENG可以轻松集成到网络中以产生高功率。这项工作为捕集水波的蓝色能量,实现野生海域自供电的海标和天气监测系统迈出了重要的一步。FB-TENG可以轻松集成到网络中以产生高功率。这项工作为捕集水波的蓝色能量,实现野生海域自供电的海标和天气监测系统迈出了重要的一步。
