This review provides a comprehensive and quantitatively supported synthesis of cutting-edge sensor technologies (2018–2025) designed for extreme environments. It investigates materials, device architectures, and system-integration strategies that facilitate operation under conditions such as high temperatures, pressures, radiation, corrosive media, hydrostatic loads, cryogenic conditions, and wireless power/data limitations. This review takes a holistic approach by integrating materials, device architectures, packaging, communication, and edge intelligence, rather than summarizing individual sensor types in isolation. It emphasizes a system-level perspective that includes quantitative performance targets and manufacturability considerations. The synthesis of studies reveals unresolved integration bottlenecks and delineates immediate research directions to develop autonomous, field-deployable, multifunctional sensor networks. A comprehensive comparison framework is presented, utilizing consistent performance descriptors, including temperature capability, sensitivity, radiation tolerance, wireless readout distance, and hermetic stability. In addition to device physics, the paper examines diverse packaging strategies, hybrid mechanisms for wireless power transfer and data transfer, and integrated data-driven calibration methods utilizing statistical and machine-learning models. Future directions suggest incorporating quantum sensing, neuromorphic computing, reconfigurable surfaces, and bio-integrated platforms to develop autonomous, adaptive sensor networks.</p>","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 16","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785151","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}

To address this issue, a low-liquid-supply preparation strategy was proposed. Superhydrophobic polyester fabrics were fabricated by atomization spraying zinc nitrate hexahydrate and 2-methylimidazole onto the fabric surface, followed by the in situ introduction of polydimethylsiloxane at room temperature. The scanning electron microscopy images showed the formation of ZIF-8/PDMS rough structures on the fiber surface without blocking the original gap structures of the PET fabric. The modified PET fabrics exhibited robust superhydrophobicity even after 100 washing cycles and 10 000 abrasion cycles. Moreover, the superhydrophobic fabrics exhibited excellent self-cleaning and antifouling properties, remarkable ultraviolet protection performance, and high oil/water separation efficiency. Notably, the UPF value of the modified fabric reached 782.68, demonstrating exceptional UV protection by blocking 99.9% of ultraviolet radiation. The oil–water separation efficiencies of the prepared PET fabric reached 97.8% for <i>n</i>-hexane and 98% for chloroform even after 20 cycles.

Differential scanning calorimetry (DSC) confirmed that TMC disrupted crystallinity to expand amorphous regions, while MH accelerated bulk erosion via water wicking and mitigated local acidification. DSC further revealed a marked increase in crystallinity through 12 months, followed by a substantial decline at 24 months, confirming the biphasic degradation mechanism.

Most prior developments employ helium (He) as the carrier gas because it enables high particle velocities and dense coatings. However, He is nearly two orders of magnitude more expensive than nitrogen (N₂), which limits its widespread adoption in the hydropower sector. Although He-based cold spray can be justified for high value repairs, the lower cost and broad availability of N₂ make it an attractive alternative. This study assesses the feasibility of N₂-based cold spray of Inconel powders for hydropower applications. Cavitation erosion testing shows that a He-based coating exhibits cavitation resistance of 398% relative to the SS304L substrate. In contrast, the N₂-based coating shows substantially lower cavitation resistance, reaching only ∼69% of the substrate, even under higher carrier gas temperature and pressure. Reducing the Inconel powder size from 44 to 22 µm significantly improves performance to ∼148% of the substrate, and further enhancement to ∼172% of the substrate is achieved by incorporating fine chromium carbide particles.

Magnetic and thermal fields can enhance melt-pool convection and acoustic fields lead to fragment dendrites. Deformation fields and external forces such as in-situ rolling or peening induce plastic strain for dynamic recrystallization.
