Apart from moisture resolution, existing sensors often lack the necessary spatial resolution, making precise control of adhesion quality difficult. To solve this problem, we present a novel experimental setup that generates controlled micrometre-scale moisture gradients in thin polymer samples, enabling high-resolution calibration of surface-sensitive moisture sensors. Since direct measurement of the moisture profile at this scale is difficult, we validated the generated moisture gradients using computational fluid dynamics simulations and confirmed their linearity and stability. We then used this setup to determine the effective detection depth of a previously developed surface moisture sensor based on diffuse reflectance infrared Fourier transform spectroscopy. Our results show that using this experimental setup alone improves the spatial resolution of the sensor by a factor of 14 – from about 0.7 mm to effectively 48 µm. This approach fills a critical gap by providing a practical means of calibrating and characterising moisture sensors that respond to surface moisture gradients, significantly improving quality control in high-precision manufacturing processes.</div></div>","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"447 ","pages":"Article 138792"},"PeriodicalIF":3.7,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its distinctive electronic structure and hydrophilic properties, ZnS exhibits a rapid response to the adsorption and desorption of water molecules. This characteristic endows it with significant potential for applications in humidity-sensitive fields. However, most conventional synthesis methods yield cubic crystalline phase ZnS, which exhibits poor stability under high humidity conditions. The research in this work shows that introducing NiS induces a cubic to hexagonal phase transition in ZnS, effectively addressing poor stability of cubic ZnS. Meanwhile, the heterogeneous interface formed between ZnS and NiS generates a synergistic effect, optimizing the charge transfer path and efficiency within the material. When water molecules are adsorbed or desorbed, the charge transfer becomes smoother, making the material more sensitive to humidity changes. Finally, ZnS-NiS was coated on the interdigital electrodes to fabricate a flexible sensor. This humidity sensor demonstrates excellent long-term stability and a short response/recovery time (0.5<!-- --> <!-- -->s/1.5<!-- --> <!-- -->s), enabling precise monitoring of human breathing, including real-time tracking of breathing rate and sleep status (snoring, deep sleep, and light sleep).

In this study, we introduce a room-temperature ammonia gas sensor based on a polyaniline (PANI)-modified Mo₂TiC₂T<em>ₓ</em> (PANI-MTC) MXene composite. The PANI-MTC composite demonstrated a high gas response of 57.8% at 100 ppm and superior selectivity over other gases. Also, the addition of PANI greatly enhanced the sensor stability, where stable gas responses were observed in humid environments and during prolonged exposure to the ambient environment. Another key feature of this study is the integration of PANI-MTC and pristine MXene electrodes into a fully printable sensor design, leveraging solution-based fabrication techniques to fabricate electrodes on arbitrary substrates. Moreover, the sensor's all-MXene architecture simplifies manufacturing, enabling scalable production using cost-efficient techniques.","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"73 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, problems such as low sensitivity, large size, and cross-sensitivity among multiple parameters have been restricting their development. Herein, a novel dual-sensing cavity Mach-Zehnder interferometer (MZI) based on hollow core fiber (HCF) is proposed for seawater temperature and salinity. To enable free seawater flow in and out, a microchannel is engraved on the air cavity of an HCF via a femtosecond laser, which is spliced between two single-mode fibers (SMFs). A D-type microcavity is machined on the cladding of the HCF and filled with temperature-sensitive material, polydimethylsiloxane (PDMS). The combination of symmetrical waveguides and PDMS makes a compact, high-sensitivity temperature sensing path. The PDMS also enlarges the difference in sensitivity between temperature and salinity. The proposed interferometer is fabricated by a femtosecond laser to form a lab only on a single short section of fiber. Experimental results demonstrate that the proposed structure exhibits high sensitivities of 2.73 nm/‰ from 0 ‰ to 40 ‰, and −5.36 nm/°C for temperature ranges between 5 °C and 45 °C.

The ETBC-TMT COF was synthesized via solvothermal method with the vinylene-linked Knoevenagel condensation.

The basophil activation test (BAT) has emerged as a promising functional assay, involving the <em>ex vivo</em> stimulation of whole blood with allergens and subsequent measurement of basophil activation. The BAT has been shown to have high diagnostic accuracy. However, clinical adoption of the BAT has been limited, in part due to logistical constraints, including the requirement for fresh blood and reliance on conventional flow cytometry analysis (FCA) of fluorescently labeled activation markers such as CD63 and CD203c. Despite recent advances in automation, FCA remains restricted to research and high-complexity clinical laboratories.
