“…Recently, researchers reported a bubble motion‐based triboelectric sensor (BM‐TES) for detecting and locating blockages and leaks in a plastic tube (Figure 14e). [ 193 ] The BM‐TES consists of several annular copper electrodes distributed on a PTFE tube, which has the advantage of non‐damaging detection without an additional energy supply. When the detection bubble moves forward under the action of buoyancy, it changes the original solid‐liquid two‐phase interface into a gas‐solid‐liquid three‐phase interface, accompanied by an obvious AC output in the external circuit.…”

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.

Harnessing ambient renewable mechanical energies for achieving carbon‐neutrality demands the rational design of materials and architectures which are favorable for both energy collection and conversion simultaneously. However, the direct coupling of energy collection and conversion modules leads to many unwanted problems such as material wearing, the spatial constraint for large‐scale integration, and low energy conversion efficiency. Herein, a remote‐controlled energy harvesting strategy that cleverly harnesses the unique advantage of diffusive, long‐range airflow within a confined capillary channel is developed. The reported device separates the energy collection unit, made of an elastic cavity that directly transforms external mechanical motion to pneumatic motion, from the conversion units, made of encapsulated droplet chains that serve to translate their recurring motion within the capillary channel into electrical output. In contrast to single‐drain electrode design for electricity generation from fresh droplets in open spaces, two drain electrodes are designed to collect and release electrostatically induced charges from recurring droplets in the confined channel, respectively, thereby eliminating unwanted charge accumulation on recurring droplets and leading to efficient output performance. The integration of multiple electricity generation units with such a two‐drain electrode architecture with a single energy collector improves the design resilience and relaxes the spatial limitation.

“…There are different types of energy harvesting devices that can convert mechanical energy into electricity, including the mechanisms of electromagnetic induction [ 10 , 11 ], piezoelectric effect [ 12 , 13 ], and triboelectric effect [ 14 , 15 ]. Taking the advantages of light weight, simple structure, high power density and efficient low-frequency vibration energy scavenging, triboelectric nanogenerators (TENGs) stand out as an attractive technology for efficient mechanical energy harvesting [ 16 , 17 , 18 ]. Based on the coupling effect of triboelectrification and electrostatic induction, TENGs can efficiently collect electricity from random, irregular, and/or low-frequency energy, such as mechanical vibration [ 19 , 20 ], wind [ 21 , 22 ], body motion [ 23 , 24 ], and ocean waves [ 25 , 26 , 27 ].…”

Triboelectric nanogenerators (TENGs) stand out as an attractive form of technology for the efficient harvest of mechanical energy and the powering of wearable devices due to their light weight, simplicity, high power density, and efficient vibration energy scavenging capabilities. However, the requirement for micro/nanostructures and/or complex and expensive instruments hinders their cheap mass production, thus limiting their practical applications. By using a simple, cost-effective, fast spray-coating process, we develop high-performance UV-curable triboelectric coatings for large-scale energy harvesting. The effect of different formulations and coating compositions on the triboelectric output is investigated to design triboelectric coatings with high output performance. The TENG based on a hybrid coating exhibits high output performance of 54.5 μA current, 1228.9 V voltage, 163.6 nC transferred charge and 3.51 mW output power. Moreover, the hybrid coatings show good long-term output stability. All the results indicate that the designed triboelectric coatings show great potential for large-scale energy harvesting with the advantages of cost-effectiveness, fast fabrication, easy mass production and long-term stability.
