Herein, we reported a multifunctional active smart textile (MAST) based on electrospun PVDF/TiO₂ nanofibers for simultaneous acoustic recognition and ethanol detection. The MAST leverages the piezoelectric activity of a PVDF core scaffold to achieve highly sensitive acoustic detection, covering a wide range of sound pressure level from 60 to 97 dB with an exceptional frequency resolution of up to 1 Hz. Meanwhile, a TiO₂ shell layer was decorated on the surface of PVDF framework to provide highly selective ethanol discrimination. The devices not only accurately distinguish the vocal features among versatile living creatures with a recognition rate over 95%, but also efficiently identify various biomotions like joint bending and pressing. More importantly, the interfacial coupling of acoustoelectric core and chemoresistive shell enables autonomous encoding of exhaled ethanol into output vocal print signal with excellent linearity and reversibility. By integrating Mel-Frequency Cepstral Coefficients (MFCCs) with Dynamic Time Warping (DTW) algorithm, we developed a MAST enabled intelligent vehicle system (MIVS) capable of precisely and actively detecting speaker’s identity and degree of intoxication at the same time. This work offers a new possibility of voice-driven self-powered chemical quantification, paving the way for development of next-generation wearable intelligent textiles.","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"42 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153931","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}

In this study, a heterostructured system composed of ZIF-8 derived zinc oxide (ZnO) and perovskite CsPbBr3 quantum dots (QDs) was successfully constructed, achieving efficient detection of EA. Compared with pure ZnO, the detection performance of the ZnO/CsPbBr3 composite for EA has been significantly improved. The experimental results demonstrate that the sensor based on this composite exhibits a high response value of 21.5 toward EA at the optimal operating temperature of 180 ℃, with the response/recovery time being reduced from 7/9 s to 4/7 s. Moreover, the ZnO/CsPbBr3 composite exhibits good reproducibility and a positive linear response relationship. A series of tests show that the improvement of the gas-sensing performance of the ZnO/CsPbBr3 composite is attributed to the excellent photoelectric properties of CsPbBr3 QDs, the formation of the heterostructure, and the dual-oxygen cooperative effect. Finally, the molecular mechanism underlying the performance improvement of the ZnO/CsPbBr3 composite was comprehensively elucidated at the electronic structure level through density functional theory (DFT) calculation.

The results demonstrate that this technique improves locking accuracy by at least 13%, and remains effective even when the reference optical path exhibits absorption. Based on this technique, a 75% improvement in signal stability was achieved in low-pressure CO2 measurement, and during a continuous 9-hour measurement of varying CO concentrations, the signal fluctuation was only 0.12%, with a minimum detection limit of 25 ppb. The improvement in locking accuracy of this technique under different temperature and pressure conditions has also been verified.

This study presents a novel dual-functional fluorescent probe BHDTAZ, with dimethyl acridine (DMA) as donor and triazole (TAZ) as acceptor. It shows distinct responses to Sarin simulant diethyl chlorophosphate (DCP) and Sulfur Mustard simulant 2-chloroethyl ethyl sulfide (2-CEES) vapors: DCP induces a photoluminescence (PL) emission intensity ratio (I507/I428) of 9.3, 79 nm red-shift, and LOD of 1.25 ppb; 2-CEES causes 40% PL enhancement, 12 nm red-shift, and LOD of 1.23 ppm. Notably, naked-eye visible PL color changes occur blue-to-green for DCP, unchanged blue for 2-CEES. Mechanistic studies reveal that modulated intermolecular charge transfer (ICT) effect enables differentiation, with DCP enhancing it more potently.

The results revealed that optimizing the hydrothermal time to 12 hours resulted in ZnSnO3-2 exhibiting the highest gas response (40.48) towards 100 ppm n-butanol at 275°C, boasting a detection limit of 500 ppb. Furthermore, ZnSnO3-2 exhibits excellent gas selectivity and long-term stability. The improved sensing performance of ZnSnO3-2 was attributed to its large specific surface area and abundant oxygen vacancies. Additionally, the gas sensing mechanism for enhancing n-butanol detection was comprehensively analyzed.

Herein, for the first time a water-soluble supramolecular probe based on a host–guest chemistry between cucurbit[6]uril (CB6) and a styrylpyridine derivative (Spy), referred as Spy@CB6, was used for the colorimetric detection of TMAO in physiologically relevant matrices, including urine and human serum. The Spy@CB6 complex functions through an indicator displacement assay (IDA) mechanism, wherein TMAO efficiently displaces the Spy dye from their host-guest complexes by forming a stronger inclusion complex with CB6, resulting in distinct optical changes. This binding event enables highly sensitive detection, with low limit of detection (LOD) of 28.7 nM in urine and 7.4 nM in human serum, within clinically relevant ranges. The probe exhibits remarkable selectivity toward TMAO over ten common biological interferents and further demonstrates solid-state colorimetric responsiveness in urinated samples, highlighting its potential for point-of-care diagnostics. This work sets a new benchmark for highly sensitive TMAO detection in real biological matrices within clinically relevant concentration ranges and represents a significant advancement toward non-invasive, accessible, and patient-friendly diagnostic platforms.","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"37 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145154068","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}

This system features a robust YSZ-based electronic nose (e-nose) using a SnO2/Co3O4 composite, which demonstrates exceptional selectivity and sensitivity to breath alcohol, with a detection limit as low as 10 ppb and acceptable response/recovery (7 s/60 s) time. In addition, a millimeter-wave (MmWave) sensor and a mini camera are seamlessly integrated with the e-nose to monitor breath alcohol levels, heart rate, and facial expressions simultaneously. By employing multi-signal fusion technology, the integrated system achieves high accuracy in identifying alcohol-impaired driving, with a sensitivity of 97.14% and an accuracy of 98.67%. This innovative multi-signal synchronized monitoring system offers a promising strategy for enhancing road safety through real-time, highly accurate detection of drunk driving within vehicles.","PeriodicalId":425,"journal":{"name":"Sensors and Actuators B: Chemical","volume":"3 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145154067","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}

Through systematic optimization of component ratio (MWCNTs: 20 mg, ZSM-5: 200/400/800 mg, TOCNFs: 0.125/0.25/0.5/1 mg), the optimal element M20Z400T0.25 (MWCNTs/ZSM-5/TOCNFs=20:400:0.25) demonstrates a great humidity resistance response of 2520.15%/90% RH with a short response/recovery time of 6.5/15 s (43-90% RH), owing to the exceptional tri-phase synergy: MWCNTs establish conductive pathways, TOCNFs enable humidity- selective surface interactions, and ZSM-5 sieves provide nanochannels for rapid diffusion of water molecules.
