However, achieving sufficient power output at low magnetic field intensities (≤ 1.0 Oe) remains a challenge for the continuous operation of IoT sensors. To address this limitation, an MME generator is developed featuring dual piezoelectric single crystal macro-fiber composites (SFCs), strategically applying two stress-concentrated regions created by heavy tip-end and middle magnets in a cantilever structure. This design produced a total root mean square power output of 0.326 mW·cm−3·Oe−2 at an optimal load resistance under a low magnetic field intensity of 1.0 Oe. Remarkably, even under an extremely low magnetic field intensity of 0.1 Oe, the harvested energy sustained the continuous operation of a temperature/humidity sensor and enabled the reliable performance of multi-functional IoT sensors capable of monitoring temperature, humidity, and sound. This research not only presents an effective design for harvesting energy from low-level magnetic fields but also highlights the practicality of MME generators within IoT-enabled wireless sensor networks.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 9","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a biomaterial (chitosan-phytic acid) coated non-flammable cotton fabric-based triboelectric nanogenerator (TENG) is developed that can be used as a self-powered fire alarm system in extreme situations. A single-electrode mode-based flame-retardant TENG (FR-TENG) is fabricated using an aluminum electrode, chitosan, and phytic acid-coated cotton fabric using a layer-by-layer (LBL) self-assembly method as the active material. Structural, morphological, and thermal characterization is performed to confirm the uniform distribution of the active material in the cotton fabric. The treated cotton fabric demonstrates excellent flame retardancy and excellent self-extinguishing in the soaking and dry LBL method. In addition, the FR-TENG produces an excellent electrical output voltage, current, and charge of 62 V, 170 nA, and 17 nC. Finally, the FR-TENG is used as a fire alarm system integrated with a programmed microcontroller unit, where a warning LED lights up when some fire situations occur, followed by a fire alarm on the screen to initiate a rescue operation.

However, existing materials often encounter trade-offs among energy density, power density, and cycling stability. To overcome these limitations, a 2D imide-linked polyoxometalate-covalent organic framework (i-POCOF) is introduced. This hybrid material combines the redox activity of polyoxometalates (POMs) with the structural adaptability of covalent organic frameworks (COFs). Complementarily, 0D imide-functionalized POM-molecule and 1D POM-polymer systems are investigated, enabling a systematic evaluation of how dimensionality affects their physicochemical properties and electrochemical performance. By increasing dimensionality, the hybrids exhibit improved surface area ranging from 107 m2 g−1 for 0D to 257 m2 g−1 for 2D, and optimized porosity (average pore size from 1.9 nm for 0D to 3.7 nm for 2D), resulting in enhanced ion diffusion and charge transport. In particular, 2D i-POCOF exhibits remarkable electrochemical performance, achieving a specific capacitance of 132 F g−1, energy density of 73.3 Wh kg−1, and power density of 0.9 kW kg−1, with only 6% capacitance loss after 5000 cycles. These findings highlight the potential of POM hybrids as high-performance and stable energy storage hybrids, providing a promising pathway to overcome current limitations in electrode materials.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 9","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.202500356","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coating's mechanical and chemical stability is systematically evaluated under UV exposure, sonication-induced vibration, and cyclic regeneration using chemical washing. Scaffold design parameters, including pore architecture, surface topology, and chemistry, are optimized to enhance nanocomposite loading and retention. Among the tested infill designs, the gyroid structure provides the highest surface area (3259.2 mm2) and supports the largest nanocomposite mass. Incorporation of polydopamine as a bioadhesive significantly improves coating adhesion (378% increase in nanocomposite loading) and stability (200% reduction in leaching). Surface engineering also facilitates the formation of uniform, few-layer coatings, resulting in a removal efficiency of 93% within 120 min, which is comparable to that of colloidal nanocomposites reported in the literature.

In this study, Ag particles are first incorporated into PEDOT:PSS ink to produce PEDOT:PSS/Ag composite electrode materials, which are then used to construct paper-based flexible supercapacitors via a scalable screen-printing technique. Benefiting from the improved electrical property and surface morphology, the areal capacitance of the supercapacitor based on PEDOT:PSS/Ag composite electrodes is found to be 3.87 times greater than that of the pure PEDOT:PSS electrode. Moreover, the paper-based supercapacitor also exhibits exceptional flexibility, maintaining over 80% of its initial capacitance even after 9000 bending cycles.
