“…Therefore, evaluating the comprehensive situation of various preparation methods is the top priority for researchers. We have consulted a large number of articles and conducted in-depth evaluations on the preparation of triboelectric sensors using 3D printing [106][107][108][109][110][111][112], MEMS technology [41,[113][114][115][116][117][118][119][120], textile processes [64,[121][122][123][124][125][126][127], template-assisted methods [128][129][130][131][132][133][134], and materials synthesis methods [86,87,[135][136][137][138]. We have proposed evaluating the various benefits of various preparation processes, including material selection (figure 8 In terms of material selection, we evaluate it from the aspects of material type, material properties, ability to prepare microstructures, ability to doped, and sustainability; in terms of technical maturity, we mainly evaluate from application cases, standardization and normalization, process stability, technology iteration speed, and industry recognition; in terms of process difficulty, we mainly evaluate the batch production capacity, complexity of process flow, difficulty in parameter control, difficulty in material processing, and yield rate; in terms of preparation efficiency, we mainly evaluate production speed, automation level, batch production capacity, process cycle time, and material utilizat...…”

With the arrival of intelligent terminals, triboelectric nanogenerators (TENGs), as a new kind of energy converter, are considered one of the most important technologies for the next generation of intelligent electronics. As a self-powered sensor, it can greatly reduce the power consumption of the entire sensing system by transforming external mechanical energy to electricity. However, the fabrication method of triboelectric sensors largely determines their functionality and performance. This review provides an overview of various methods used to fabricate triboelectric sensors, with a focus on the processes of micro-electro-mechanical systems (MEMS) technology, three-dimensional (3D) printing, textile methods, template-assisted methods, and material synthesis methods for manufacturing. The working mechanisms and suitable application scenarios of various methods are outlined. Subsequently, the advantages and disadvantages of various methods are summarized, and reference schemes for the subsequent application of these methods are included. Finally, the opportunities and challenges faced by different methods are discussed, as well as their potential for application in various intelligent systems in the Internet of Things (IoT).

“…By incorporating poly (vinylidene fluoride-co-hexafluoropropylene) [P(VDF-HFP)] into the PDMS prepolymer and using NaCl as a template, composite sponges were prepared, further improving the electrical output performance. The obtained PDMS sponges were paired with aluminum plates to assemble TENGs for insoles, which can serve as self-powered foot pressure sensors to sense various human activities [ 29 ].…”

Porous materials possess advantages such as rich pore structures, a large surface area, low relative density, high specific strength, and good breathability. They have broad prospects in the development of a high-performance Triboelectric Nanogenerator (TENG) and self-powered sensing fields. This paper elaborates on the structural forms and construction methods of porous materials in existing TENG, including aerogels, foam sponges, electrospinning, 3D printing, and fabric structures. The research progress of porous materials in improving TENG performance is systematically summarized, with a focus on discussing design strategies of porous structures to enhance the TENG mechanical performance, frictional electrical performance, and environmental tolerance. The current applications of porous-material-based TENG in self-powered sensing such as pressure sensing, health monitoring, and human–machine interactions are introduced, and future development directions and challenges are discussed.

Corrosion, a damage phenomenon experienced by all materials in nature, causes huge losses, resource consumption, environmental pollution, industrial accidents, and endangered human health and safety. According to relevant statistics, the annual corrosion loss accounts for %3.34% of the gross domestic product (GDP), [1] and the global corrosion cost is more than four trillion dollars per year. [2] In electrochemical corrosion protection technology, cathodic protection using a sacrificial anode has the problem of metal consumption, [3] whereas cathodic protection using impressed current requires an external power supply, which requires further improvement. [4,5] In 2012, Wang Zhonglin first developed triboelectric nanogenerators (TENGs) by coupling the effects of triboelectrification and electrostatic induction. [6] TENGs have four basic working modes and can harvest different forms of energy, including human motion, [7] vibration, [8] tire rotation, [9] wind energy, [10,11] water energy, [12,13] etc. TENGs have the advantages of being light weight and low cost, with diverse structures and a wide choice of component materials, [14] along with high efficiency, even at low operating frequencies. [15] Many studies have combined TENG and impressed current cathodic protection to achieve energy harvesting and self-utilization. [16] Zhu used energy harvested from raindrops and wind for self-powered corrosion protection of metal surfaces. [17] Sun used liquid-solid TENG arrays for cathodic protection of carbon steel, [18,19] and Cui combined the self-powered cathodic protection of a sandwich-structured TENG with a green corrosion inhibitor.
