recent years to alleviate the global energy shortage and environmental pollution. They have promising applications as sustainable power sources for widely distributed sensor networks in the new era of the Internet of Things (IoT). The clean raindrop and solar energies both possess merits of wide distribution and high energy density, but they are closely related to the weather conditions. In this regard, combining them to realize complementary energy collection has been proven to be one of the effective solutions to achieve all-weather and sustainable energy supply. Due to the characteristics of widespread distribution, low frequency and limited driving force, the raindrop energy cannot be effectively harvested by traditional hydraulic power generator, which is usually heavy, bulky, and needs larger driving force to achieve high conversion efficiency at high frequency. [1] Since the invention of triboelectric nanogenerator (TENG) in 2012, [2] it has been extensively investigated because of the advantages of light weight, small size, wide material selection, low cost, [3][4][5] and even high efficiency at low frequency, [6] etc., and provides an effective approach for converting raindrop energy into electricity.Previous raindrop TENGs (R-TENGs), by coupling triboelectrification and electrostatic induction effects, were usually designed with single-electrode [7][8][9][10][11] or interdigitated electrode structures [12][13][14][15] to produce electricity. However, their electric outputs are relatively low because of the inefficient utilization of surface charges on dielectric layers. Recently, a new R-TENG, which converts conventional interfacial effect at solid-liquid interfaces into bulk effect, was proposed to effectively utilize the surface charges, and generate a high-power density up to 50.10 W m −2 , [16] which further greatly promotes the research interests about raindrop energy harvesting. Since that, many efforts have been devoted to further improving the performance of such TENG, [17,18] revealing its working mechanism, [19][20][21] and realizing different application scenarios. [22][23][24][25][26][27][28][29] Specifically, the complementary harvesting of raindrop and solar energies provides more efficient, reliable and sustainable energy supply, which has aroused wide interests from different research communities.

However, due to the irregularity of natural rainfalls in the volume, frequency, density, and location, designing high-efficiency raindrop TENG (R-TENG) arrays faces great challenges. In this work, a highly transparent, large-area, and high-efficiency R-TENG array with rational material choice, electrode s...

“…This TC-TENG can utilize multi-channel to simultaneously harvest irregular high-entropy droplet energy from water sources such as rain, streams, waterfalls and fountains, and then converge energy on electrodes and directly convert it into DC output without a rectifier unit. In contrast, using the reported AC-TENGs such as droplet-based TENGs 13 and transistor-like DEGs, 37 it is difficult to achieve a perfect array design without a rectifier. This is because when AC-TENGs are used to build a large-scale network, the electricity generated by different nanogenerators have to be phase-synchronized or rectified before being integrated into the power grid due to frequency inconsistencies.…”

Harvesting water energy in various forms of water motion, such as evaporation, raindrops, river flows, ocean waves, and other, is promising to relieve the global energy crisis and reach the aim of carbon neutrality. However, this highly decentralized and distributed water energy poses a challenge on conventional electromagnetic hydropower technologies that feature centralization and scalization.Recently, this problem has been gradually addressed by the emergence of a myriad of electricity generators that take inspiration from natural living organisms, which have the capability to efficiently process and manage water and energy for survival in the natural competition. Imitating the liquid-solid behaviors manifested in ubiquitous biological processes, these generators allow for the efficient energy conversion from water-solid interaction into the charge transfer or electrical output under natural driving, such as gravity and solar power. However, in spite of the rapid development of the field, a fundamental understanding of these generators and their ability to bridge the gap between the fundamentals and the practical applications remains elusive. In this review, we first introduce the latest progress in the fundamental understanding in bio-inspired electricity generators that allow for efficient harvesting water energy in various forms, ranging from water evaporation, droplet to wave or flow, and then summarize the development of the engineering design of the various bio-inspired electricity generator in the practical applications, including self-powered sensor and wearable electronics. Finally, the prospects and urgent problems, such as how to achieve large-scale electricity generation, are presented.
