“…In addition to water, organic liquids like ethylene glycol also respond favorably to temperature in terms of electrical production. In accordance with Figure 6c–e, M. Feng et al [ 40 ] built a reversible thermosensitive liquid–solid TENG (L‐S TENG) based on another temperature‐sensitive material P(NIPAM‐MMA) (PNM) copolymer in order to achieve tunable triboelectrification. The interfacial wettability and triboelectricity of PNM modify the conformation between the acylamino and isopropyl groups through temperature modulation.…”

Liquid–solid contact electrification is a universal physical phenomenon. The electrical energy produced by a drop of water during the solid–liquid triboelectric electrification (TE) process is negligible, usually at the level of nA or uA. However, by adjusting the structure and composition of materials, or by designing devices more rationally, TE of a drop of water can reach voltages in the thousands of volts and currents in the mA level, which is sufficient to power many electronic devices. Therefore, studying solid–liquid triboelectric nanogenerators is of great significance in the field of energy harvesting. To achieve the manipulation of liquid–solid triboelectrification to nurture strengths and bypass weaknesses, a thorough knowledge of the liquid–solid contact electrification process and its influencing elements is required. The concept, influencing variables, mechanisms, and current control tactics of solid–liquid triboelectrification are addressed in this review. Then, using triboelectric generator technology, solid friction layers are designed and fabricated from three perspectives: structure design, surface functionalization modification, and interface wettability control, with discussion of how the three factors interact and contribute to solid–liquid electrification behavior. How solid–liquid triboelectrification can be used to capture energy and create self‐powered sensors is discussed.

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.

Solid‐liquid triboelectric nanogenerators (SL‐TENGs) are a new technology that combines contact electrification (CE) and electrostatic induction to collect clean energy stored in natural water. Considering their unique advantages of high energy density, wide selection of materials and being suitable for large‐scale promotion, they have attracted more and more attention in recent years, and numerous studies have shown their great potential in various applications. Many critical applications of SL‐TENGs inevitably involve sustained and stable high electrical output. To achieve stable output performance and long cycle life in these applications, the adaptability of SL‐TENGs to material selection, structural design, and working environment is necessary. Therefore, the construction of SL‐TENGs matching different applications has become a critical research direction in TENGs. This review provides a historical summary of the development of SL‐TENGs in the past few years and analyzes the key factors affecting their electrical output performance. The exciting achievements of different constructions of SL‐TENGs for practical applications is also demonstrated such as energy harvesting, self‐powered sensing, and self‐powered cathodic protection. Finally, the development prospects of SL‐TENGs and the significant challenges for their further development is discussed.
