However, most t-TENGs are fabricated using physical or chemical processes to give the materials specific properties, with the disadvantages of high material requirements, complex and time-consuming fabrication processes, and impact on the comfort of the textiles. In this study, a three-dimensional woven triboelectric nanogenerator (3DW-TENG) with integrated friction, spacer, and electrode layers was fabricated by using a three-dimensional weaving technology. By combining experimental testing and theoretical analysis, the study investigated the impact of the arrangement of friction materials and the number of friction layers on the performance of the 3DW-TENG. At a frequency of 1<!-- --> <!-- -->Hz and under an external force of 30<!-- --> <!-- -->N, the open-circuit voltage, short-circuit current, and peak power density of the 3DW-TENG reached 9.38<!-- --> <!-- -->V, 31.65<!-- --> <!-- -->nA, and 2.16 × 10^{-2<!-- -->}mW/m². The three-dimensional fabric structure gave it better integrity and stability. In addition, the 3DW-TENG exhibited excellent flexibility and sensitivity, which allowed for better integration with textiles. It was capable of converting mechanical energy into electrical energy and powering micro-devices. It could also sensitively detect the bending and changes in the motion state at important joints. When placed at the sole of the foot, it could serve as a self-powered pressure sensor to identify changes in foot pressure. This work provides greater development space for the potential applications of flexible self-powered textiles in the fields of wearable electronics and personalized healthcare.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"25 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142884707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work draws inspiration from the three-dimensional microstructure of the superhydrophobic lotus leaf surface and transfers the microstructure from nano-SiO₂ to Ecoflex surface. A self-powered, low-cost, highly durable, and stable triboelectric nanogenerator (TENG) was thus developed for earthquake warning based on the superhydrophobic, self-cleaning, and flame-retardant film.

In addition, there is a strong linear correlation (The R² value is 0.98 and 0.99.) between peak current and vibration acceleration and vibration when the EW-TENG is applied to different vibration intensities.

Then, the real-time monitoring capability of the EW-TENG is verified in a more realistic simulated geological disaster scenario.

Evaporation and condensation are the two main processes that extract or release energy from the environment.

Here we demonstrate that the energy can be converted into electricity in situ through the hydrovoltaic effect within the soil itself. The soil-based hydrovoltaic electricity generators exhibit excellent reproducibility and stability, demonstrating the potential for scalable integration. A series voltage of over 13.4<!-- --> <!-- -->V was achieved, placing it in the top five of integrated devices reported to date. By designing an integrated module suitable for amplifying natural electricity from both soil evaporation and soil condensation process, a parallel current of up to 18.62 μA (0.06 m²) was obtained.

In this study, a photo-thermoelectric supramolecular thermosensitive hydrogel (SPTP-Cu) is synthesized, which can achieve a centripetal current, controllable contraction, and effectuate antibacterial cooperation to accelerate wound closure and re-epithelization through a single NIR input on the hydrogel center. In addition, SPTP-Cu hydrogel demonstrates remarkable injectability, fast self-healing, a strong antioxidant, and rapid hemostatic without residual. In the rat infection wound repair experiment, SPTP-Cu + NIR treatment can effectively promote angiogenesis, collagen deposition, and re-epithelialization, achieving tissue remodeling in a short period (12 days).

Semiconductor-based monolayered two-dimensional transition-metal dichalcogenides exhibit superior mechanical, electrical, and optical characteristics than other materials. We used triangular MoSe₂ monolayers to fabricate two-terminal flexible devices and studied strain-dependent behaviors such as the interface barrier between the metal electrode and semiconductor by piezotronic phenomena. Our electrical and topography results showed that the interface barrier between a Pt electrode and MoSe₂ monolayer increases with increasing tensile strength and decreases with increasing compressive strain due to the strain-modulated increase and decrease of the energy barrier in the fabricated semiconductor. The flexible device was operated at a low voltage of 1<!-- --> <!-- -->V as the ON condition in the tensile mode and OFF condition in the compressive mode. Furthermore, the strain-dependent interface barrier impacted the photoresponse characteristics in the MoSe₂ monolayer through energy bending bands, which influenced the electron–hole recombination by photogenerated carrier transport.
