The fiber-optic coil (FOC), as the core sensing component of an interferometric FOA, plays a crucial role in determining the sensor’s sensitivity through its strain distribution characteristics on the transducer plate. This article presents, for the first time, the novel introduction of noncircular FOCs (NC-FOCs), which are employed in the design of a rectangular thin-plate FOA and plate-tpye FOA (PT-FOA) to improve low-frequency detection performance. In this study, the finite element method (FEM) and tensor analysis theory are employed to establish a universal model for PT-FOA constructed with NC-FOCs. Sensors with FOCs of various shapes were designed, fabricated, and tested. Both theoretical and experimental results demonstrate that different shapes of FOCs can improve sensitivity by approximately 14.62%. The underlying mechanisms of these improvements are analyzed by studying the strain tensor distribution on the transducer plate. The proposed PT-FOA addresses the limitations of existing FOAs in low-frequency detection. The sensitivity enhancement method maintains the same resonant frequency and thermal noise levels while significantly improving the signal-to-noise ratio (SNR) and sensitivity of the sensor. This work provides a general modeling approach and valuable practical guidance for the design and optimization of high-sensitivity FOAs, with important implications for both research and application.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 9","pages":"15080-15091"},"PeriodicalIF":4.3,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To obtain a large-scale and high-performance near-zero magnetic environment, this article presents a coil design method based on the boundary element method (BEM) for compensating the nonuniform static magnetic field existing in the magnetic shielding room (MSR). To achieve precise compensation of nonuniform magnetic field, BEM-based image method is introduced to eliminate the deviation by coupling between the magnetic field generated by the coil and the magnetic shielding material, and the gray wolf optimization (GWO) algorithm is employed for the optimal design of coils.

Therefore, it is necessary to monitor the concentration of ethylene glycol in the environment. Metal oxide semiconductors (MOSs) exhibit good response to ethylene glycol gas. However, previous reports on ethylene glycol sensors have drawbacks such as high operating temperature and high-energy consumption, which cannot perfectly meet the needs of practical life.

The results showed that the response value of 7% Er/ZnO to 100 ppm ethylene glycol was as high as 156.6, while retaining high selectivity for ethylene glycol gas. The combination of high response value of ethylene glycol and lower operating temperature near room temperature indicates that the sensor based on 7% Er/ZnO achieves a balance between sensitivity, response value, and operating temperature. UV spectroscopy and photoluminescence (PL) spectroscopy characterization confirmed that the energy levels of Er2O3 composite ZnO changed, effectively extending the lifetime of photograph-generated carriers.

It is designed to harvest energy from a relatively wideband ambient vibrational source. The proposed harvester has a conventional piezoelectric cantilever with a magnetic proof mass, coupled in a magnetically repelling orientation to another U-structure, which also has a magnetic proof mass. When the source vibrates with different frequencies, both structures vibrate with different amplitudes depending on their respective resonant frequencies. However, due to the magnetic coupling, the overall output extracted from the piezoelectric cantilever is higher compared to having two independent piezoelectric cantilevers. Moreover, the magnetic coupling imparts more nonlinearity into the system, widening the frequency bandwidth where maximum energy harvesting occurs. Apart from the overall efficiency, the gain at a specific target frequency range can be improved by selecting the physical parameters of the U-structure so that its resonant frequency is driven to be within this range. Also, the resonant frequency of the piezoelectric cantilever can be tuned by altering the magnetic coupling, which indirectly changes the stiffness of the cantilever. This can be easily done by adjusting the distance between the magnets. Therefore, the proposed prototype broadens the frequency bandwidth while being very simple, economical, and requiring minimal maintenance. A theoretical study and an analytical analysis were performed on the prototype. Laboratory and field experiments demonstrated the benefits and better performance of the proposed prototype with respect to key parameters such as frequency bandwidth, total harvested power, reduction in charging time of a capacitor, and scalability.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 9","pages":"16090-16100"},"PeriodicalIF":4.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multicurrent method further reduced the uncertainty, even though this reduction diminished as the number of excitation currents increased. The multicurrent method increased the measurement time and experimental complexity. The self-heating effect and its uncertainty reduced with increasing temperature. Considering both measurement uncertainty and ease of implementation, an improved two-current method with a current ratio of 1:2 is suggested for the accurate measurement and correction of self-heating effects in thermistor thermometers. The self-heating effect from the measured resistance value across all temperature ranges should be corrected to ensure accurate and precise temperature measurements.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 9","pages":"14688-14695"},"PeriodicalIF":4.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typical DNs have hundreds of VFDs spread over a much larger area, it is impractical to represent each of the VFD explicitly. To find a reasonable representation that can reproduce the important behavior of different VFDs, a low-order generic model for different types of VFDs is developed. Then, we propose a new method for aggregating the generic VFD models, which provides detailed equivalence for the linear and nonlinear components and therefore has high accuracy. Finally, the aggregated VFD model is paralleled with the traditional composite load model (CLM), named variable frequency drives-composite load model (VFD-CLM), which is used to describe the overall dynamics of the DNs containing a high share of VFDs. Based on a practical DN with multiple types of VFDs, both the feasibility and applicability of the proposed VFD-CLM model are verified under different voltage dip faults. The proposed VFD model is low-order and generic, which can be easily implemented into the existing simulation platforms. In addition, the developed VFD-CLM model is much more accurate, which is beneficial for power system analysis and control.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 9","pages":"15247-15260"},"PeriodicalIF":4.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretically, the tightly coupled (TC) solution of the dual-antenna baseline constraint and MEMS INS offers better attitude accuracy. However, its state space is incomplete, comprising only attitude, gyro biases, and ambiguity. Moreover, previous studies have not conducted a state observability analysis on this model, which is essential for understanding its state estimation capabilities. Therefore, we derived the TC model of dual-antenna baseline constraint and MEMS INS within a complete state space and performed an observability analysis. Based on these results and considering computational efficiency, we integrated this model into the GNSS/MEMS INS TC model using federated filtering. To further improve the algorithm’s accuracy in complex agricultural environments, an adaptive robust positioning algorithm is proposed based on turning state detection.
