The energy crisis is a continuing topic for all human beings, threatening the development of human society. Accordingly, harvesting energy from the surrounding environment, such as wind, water flow and solar power, has become a promising direction for the research community. Water contains tremendous energy in a variety of forms, such as rivers, ocean waves, tides, and raindrops. Among them, raindrop energy is the most abundant. Raindrop energy not only can complement other forms of energy, such as solar energy, but also have potential applications in wearable and universal energy collectors. Over the past few years, droplet-based electricity nanogenerators (DENG) have attracted significant attention due to their advantages of small size and high power. To date, a variety of fundamental materials and ingenious structural designs have been proposed to achieve efficient droplet-based energy harvesting. The research and application of DENG in various fields have received widespread attention. In this review, we focus on the fundamental mechanism and recent progress of droplet-based nanogenerators in the following three aspects: droplet properties, energy harvesting and self-powered sensing. Finally, some challenges and further outlook for droplet-based nanogenerators are discussed to boost the future development of this promising field.
能源危机一直是全人类关注的话题，威胁着人类社会的发展。因此，从周围环境中获取能量，如风能、水流能和太阳能，已成为研究界一个很有前景的方向。水以多种形式蕴含着巨大的能量，如河流、海浪、潮汐和雨滴。其中，雨滴能量最为丰富。雨滴能量不仅可以补充太阳能等其他形式的能量，还在可穿戴和通用能量收集器方面具有潜在应用。在过去几年中，基于液滴的电纳米发电机（DENG）因其体积小、功率高的优点而备受关注。迄今为止，人们已经提出了各种基础材料和巧妙的结构设计，以实现高效的基于液滴的能量收集。DENG在各个领域的研究和应用受到了广泛关注。在这篇综述中，我们将从以下三个方面重点关注基于液滴的纳米发电机的基本机制和最新进展：液滴特性、能量收集和自供电传感。最后，讨论了基于液滴的纳米发电机面临的一些挑战和进一步的展望，以推动这一有前景领域的未来发展。
