“…With the rapid development of economy and technology, the sustainable development of human society has an increasing energy demand. A large amount of renewable clean energy is stored in natural water in the form of droplets, [1][2][3][4] waves, [5][6][7][8][9][10] flows, [11][12][13][14] and others. [15][16][17][18] Considering that most of these energy sources have the characteristics of low frequency, wide distribution and irregularity, it is not easy to use traditional electromagnetic power generation equipment to collect and utilize them.…”

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.

“…There are various forms of energy sources available like kinetic, biochemical, thermal, and solar energy [6]. Among these energy sources, the kinetic energy is abundantly available, which can be produced by external environments such as wind [7,8], rain [9], and water wave [10]; by human body movements such as walking [11], running [12], jumping [13], and joint motion [14]; by physiological motion such as heartbeat [15,16], respiration [17], arterial pulse [18][19][20], and gastrointestinal motility [21]. There are three main transduction mechanisms focused by most studies for kinetic energy harvesting, including electromagnetism, piezoelectricity, and triboelectricity [22].…”

Piezoelectric materials play an increasingly important role in energy harvesters, sensors, and actuators. Flexible and thin piezoelectric films have been demonstrated to provide advanced functionalities and improved performances. However, the research on flexible inorganic piezoelectric thin films has rarely been systematically summarized. Here, we summarize the recent advances in the flexible inorganic piezoelectric thin films, focusing on their structural designs, fabrication techniques, and applications in various practical scenarios. Specifically, different fabrication techniques suitable for diverse inorganic piezoelectric nanostructures are reviewed, including sol-gel, hydrothermal, electrospinning, and other techniques, and the integration process with flexible substrates is further discussed. Biomedical and industrial applications of the flexible piezoelectric thin films are emphasized. Finally, some existing challenges and future perspectives are discussed.

“…Triboelectric Nanogenerator (TENG) is an emerging energy harvesting technology, which is an effective approach to address such issues. As shown in Figure 1a, TENGs can collect lowgrade energies from the environment, such as oceanic energy, [4][5][6][7] mechanical energy, [8,9] raindrop energy, [10][11][12] wind energy, [13][14][15] and human motion energy, [16][17][18] and convert them into electrical energy for electronic devices. However, TENG exhibits these characteristics of pulse output, ultra-high voltage (kV), ultra-high impedance (MΩ), and low current output (μA), which makes it challenging to effectively transmit the generated energy to the load end for efficient utilization.…”

Spark discharge is essential for extracting energy from triboelectric nanogenerators (TENGs). However, the lack of universal technical standards for most discharge switches limits their widespread application. Herein, a buck circuit utilizing gas discharge tube (GDT) as discharge switches is presented. The GDT switch significantly enhances the instantaneous power to 30 mW, 15 times higher than the direct method. When VGDT (the breakdown voltage of GDT) ≤1000 V, it can be integrated with an LC converter, forming the GDTx‐Buck circuit with a maximum energy conversion efficiency of 92.2%. When VGDT >1000 V, GDT can combine with a transformer, forming the GDT‐nT circuit, which enables higher voltage power management. The results demonstrate GDT's universal applicability, reducing circuit complexity during design. In practical applications, the circuit can illuminate 1250 LEDs at an ultra‐low operating frequency of 0.6 Hz, generating electromagnetic waves during GDT breakover, which proves valuable for self‐powered wireless applications. Additionally, the circuit drives parallel calculators and thermometers at 2 Hz in micro‐nano energy applications and provides continuous power to high‐power fire sensors. Its high integration and simple design render it highly promising for large‐scale energy management applications based on TENGs.
