These analyses confirmed the uniformity and purity of the nanowires.

Nonetheless, most of the available sensors 1) require as many sensors as there are muscles to monitor, resulting in a time-consuming preparation for practical use and 2) present a nonelastic nature, entailing a customized design to the user’s segment anthropometries. Thereby, we developed the MuscLab system, which uses e-textile (piezoresistive textile) sensors sewn onto a flexible and elastic textile band. It simultaneously monitors and discriminates muscle contractions across different muscle groups in individuals with a shank perimeter ranging from 33.5 to 48.7 cm. From a benchmark analysis involving ten non-disabled individuals, the MuscLab was able to 1) detect muscle contractions at different motion cadences, with an average delay of 135.8 ± 78.0 ms and strong spearman correlation (0.78 ± 0.08) regarding EMG signals of tibialis anterior (TA) and gastrocnemius lateralis (GALs) and 2) distinguish different levels of muscle contraction performed at different ankle joint angles (the average coefficient of determination of 0.92 ± 0.10 and 0.89 ± 0.16 for ankle dorsiflexion and plantar flexion movements, respectively). This research advances with new insights regarding the use of e-textiles in an elastic band for monitoring the multimuscle contraction of users with different anthropometries.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 6","pages":"9478-9485"},"PeriodicalIF":4.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621712","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}

Radar technology has attracted much attention because of its unique advantages such as not being limited by environmental conditions such as light, shadow, and occlusion. In this article, a continuous HAR system based on multidomain radar data fusion (CMDN) is proposed. Firstly, in order to capture more detailed motion features of the human body, we apply the short-time fractional Fourier transform (STFrFT) to map radar data into the fractional domain, yielding a novel representation of human motion. Secondly, we develop an activity detector based on variable window length short-time average/long-time average (VW-STA/LTA) to accurately identify the start/end points of continuous human actions, addressing the challenge of difficult sequence segmentation in continuous activity recognition tasks. Finally, based on the multi-input multitask (MIMT) recognition network, the features of each domain are processed in parallel, and multiple input representations are fused to obtain the continuous activity classification results with high precision.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 6","pages":"10432-10443"},"PeriodicalIF":4.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621747","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}

This study proposes the use of a high-frequency resonance eddy current (R-ECT) sensor and a multiphysical field fusion method to address this issue. Initially, high-frequency resonance technology is employed, whereby not only is an eddy current secondary magnetic field generated but also an electric field in the gap between the planar coil and the metal. Therefore, the excitation of a multiphysical field in eddy current sensors has been achieved. Second, a probe multiparameter separation algorithm is proposed. Consequently, the separation of the magnetic and electric fields can be achieved. The results of experiments conducted on 12CrMoV steel demonstrate that the parameter capacitance relating to electric fields is more accurate and linear than the parameters resistance and inductance relating to eddy current secondary magnetic fields. Finally, the multiparameter and multiphysical field fusion method is discussed in order to enhance the accuracy of thermal aging characterization. The results of the experiments demonstrate that the fusion characterization method, which combines resistance and capacitance, leads to a significant reduction in error, by as much as 80%, when applied to the characterization of eddy current magnetic fields and gap electric fields.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 6","pages":"10145-10154"},"PeriodicalIF":4.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621654","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}

However, the measurement of these human body kinematic parameters is now possible using a tiny, inexpensive, and portable wearable inertial measurement unit (IMU). The primary objective of this research is to assess the feasibility and accuracy of upper body kinematic measurement using multiple IMUs. The analysis in this study has considered the elbow and wrist joint angles, and the 12 healthy participants performed the assigned wrist (flexion/extension) and elbow (flexion/extension) movements with both hands. Three IMUs were used to measure the motion, and each joint angle was also measured with an electrogoniometer (EG). The data obtained from the IMUs were used to determine the joint angle, and the mean absolute error (MAE), mean squared error (MSE), and root-mean-square errors (RMSEs) were computed in comparison to the EG readings to evaluate the performance. An average RMSEs of 2.35° and 2.30° for elbow and wrist, respectively, were found for joint motion among the 12 subjects for all tasks. The maximum RMSE for both elbow and wrist joint angles was less than 5°, except for one measurement. A graphical user interface (GUI) was also designed and developed to help clinicians and therapists to assess patient progress, provide feedback, and motivate patients. The outcomes of our study revealed that the IMU system could be used to assess the upper extremity joint angles during functional motions.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 6","pages":"9467-9477"},"PeriodicalIF":4.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621664","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}

Conventional VTS-PS, such as GelSight, typically assume directional and uniform illumination to simplify the algorithm of photometric stereo. However, this assumption poses stringent requirements on the hardware side and limits the sensors in shape, size, and flexibility for various applications. Additionally, the configuration of directional lighting exacerbates the issue of cast shadowing. In this article, we analyze the benefits of point lighting over conventional directional lighting for VTS-PS and propose GelPoLight, a novel VTS-PS with point lighting, which can help handle or alleviate the aforementioned problems. GelPoLight does not assume ideal diffuse reflectance for the reflective membrane and considers the varying influencing factors of light intensity, light directions, and reflectance factors in the estimation of surface normal vectors. Accordingly, we developed a new calibration method for this approach. We also corrected image distortions caused by light refraction, which is a prevalent issue in visual-tactile sensors (VTSs). The final results demonstrate that GelPoLight can effectively generate the contact depth map, with errors of approximately 5% in the planar direction and 8% in the depth direction.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 6","pages":"9575-9584"},"PeriodicalIF":4.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621850","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}

GNSS carrier phase measurements can provide high-accuracy measurements, enhancing positioning performance. Unfortunately, the accuracy of scalar-tracking loop carrier phase measurements significantly deteriorates in complex environments. This decline arises partly from the underutilization of received information by scalar-tracking loops. The hybrid vector-scalar architecture combines the robustness of carrier frequency tracking with the accuracy of the scalar phase-locked loop (PLL), making it an excellent carrier-tracking method. However, the capricious nature of the rule-of-thumb parameter settings and the associated complexity limit the full exploitation of the structural advantages. Therefore, we first establish a mathematical model for error propagation in the vector frequency-locked loop-assisted PLL (VFLL-assisted PLL) and derive an analytical expression for the phase error. Then, an optimal parameter setting approach based on the minimum error criterion is proposed. Finally, the carrier-tracking performance of the VFLL-assisted PLL with the optimal parameter design approach is evaluated. The assessment and evaluation are conducted via experiments with simulated and real data. The results indicate that the optimal parameter design approach improves the carrier-tracking performance of the VFLL-assisted PLL, which is more sensitive and dynamic than the FLL-assisted PLL.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 6","pages":"9790-9801"},"PeriodicalIF":4.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621921","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}
