This study presents chemiresistive sensors based on 3-D hierarchical structures consisting of zinc oxide (ZnO<italic>x) and copper oxide (CuO<italic>y) microwires covered with nanowires. The hierarchical sensors, fabricated by heating the microwires, exhibit good sensing performance at room temperature for glucose and lactate solutions. The ZnO<italic>x sensor, while maintaining a lower resistance than in air, exhibits concentration-dependent responses: its resistance decreases for glucose but increases for lactate. By contrast, the resistance of the CuO<italic>y sensor consistently increases with increasing concentration of both analytes. Furthermore, with increasing analyte concentrations, the response time of the ZnO<italic>x sensor increases for both analytes, whereas that of the CuO<italic>y sensor increases for glucose and decreases for lactate. These distinct sensing behaviors suggest unique surface interactions in aqueous solution. This study demonstrates that the synergy between 3-D hierarchical structures and multiparameter sensing enables effective biomarker identification at room temperature.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 7","pages":"2001704-2001704"},"PeriodicalIF":2.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148505757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing phantoms often fail to maintain stable hydration or lack tunable electrical properties, limiting their effectiveness for electrode benchmarking. This study introduces a porosity-engineered, two-layer skin phantom in which the upper polydimethylsiloxane (PDMS) layer is laser-patterned to control pore density, enabling predictable modulation of hydration, permittivity, and impedance. Measurements performed on the fully assembled phantom demonstrate that increasing porosity produces a coupled increase in permittivity and decrease in impedance, following well-defined power-law relationships. These trends mirror the dielectric behavior of biological skin across dry-to-hydrated states and allow porosity to function as a structural proxy for hydration level. Using this relationship, porosity was mapped to operational hydration states ranging from very dry (0% porosity) to moderately hydrated (10% porosity). Lower-porosity phantoms exhibited improved hydration stability and extended electrical lifespan, whereas higher porosity samples showed accelerated dehydration and reduced mechanical robustness. The phantom’s tunable electrical properties enabled direct comparison of commercial dry electrodes, revealing distinct impedance responses among Neurotrode, Biopac Flat, JJE SE13, and JJE SE12 electrodes under controlled hydration conditions. Overall, this work establishes porosity as a quantitative design parameter for replicating hydration-dependent skin impedance and presents a scalable, physiologically relevant platform for standardized evaluation of wearable biopotential electrodes.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 7","pages":"1501204-1501204"},"PeriodicalIF":2.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148506414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This simplified architecture contrasts with conventional Au NP–GO composites, where the contribution of the GO layer is often masked, and may enable scalable fabrication. GO-modified electrodes exhibit the highest sensitivity, with two linear amperometric regimes (0–0.5 and 1–22 mM) and sensitivities of 18.7 and 502 <italic>μA mM−1 cm−2, respectively, allowing detection below 1 mM. In contrast, chemically reduced GO shows higher current density but poor sensitivity to glucose concentration changes. These results suggest that sensing performance is not governed solely by conductivity, but by the balance between sp2 network connectivity and oxygen-containing functional groups. The enhanced response of GO highlights the important role of defect-mediated surface chemistry, supporting the hypothesis that direct GO modification of Au electrodes provides an effective alternative to NP-based systems.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 7","pages":"4502104-4502104"},"PeriodicalIF":2.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148505753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional reference circuits are typically static, limiting adaptability to varying sampling rates and energy constraints, which in turn restricts the dynamic adaption of analog front-end systems. To address this, a capacitively-biased diode-based bandgap is combined with a switched-capacitor amplifier and a frequency-controlled current source, enabling a dynamic reference and amplifier whose BW and power scale with operating frequency. Through timing coordination, a fully integrated ADC-reference system is realized. Implemented in a 180-nm complementary metal oxide semiconductor (CMOS) process, the prototype achieves an signal-to-noise-and-distortion ratio (SNDR) of 55.45 dB and signal-to-noise ratio (SNR) above 53 dB from 3.1 to 31 kHz, with power scalable from 1.4 to 4.0 <inline-formula><tex-math>$mu$</tex-math></inline-formula>W.

Unlike conventional GNSS meteorology approaches based on tropospheric delay or precipitable water vapor estimation, the proposed method exploits rain-induced attenuation effects observable in high-rate C/N0 data. Relative attenuation values are derived from multiconstellation L-band signals and integrated into a tomographic reconstruction framework using an inverse Radon transform to estimate 2-D precipitation patterns in the vicinity of the receiver. The approach is validated using convective storm events recorded in August 2025 and May 2026, compared against weather radar reflectivity maps. Quantitative evaluation using mean square error, peak signal-to-noise ratio, structural similarity index, and correlation analysis demonstrates consistent spatial agreement with radar-observed rainfall structures. Although geometric and modeling limitations introduce reconstruction distortions, results confirm the feasibility of C/N0-based opportunistic rainfall sensing. The presented method highlights the potential of low-cost GNSS receivers as distributed environmental sensors for continuous precipitation monitoring.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 7","pages":"6006604-6006604"},"PeriodicalIF":2.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148505647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
