Compared to traditional rigid grippers, the use of soft grippers reduces the control complexity and the risk of damaging objects. However, it is challenging to integrate camera-based optical tactile sensing into a soft gripper without compromising the flexibility and adaptability of the fingers, while also ensuring that the precision of tactile perception remains unaffected by passive deformations of the soft structure during object contact. In this article, we demonstrate a modular soft two-fingered gripper with a 3-D-printed optical tactile sensor (the TacTip) integrated into the palm. We propose a soft-grasping strategy that includes three functions: light contact detection, grasp pose adjustment, and loss-of-contact detection so that objects of different shapes and sizes can be grasped stably and placed precisely, which we test with both artificial and household objects. By sequentially implementing these three functions, the grasp success rate progressively improves from 45% without any functions, to 59% with light contact detection, 90% with grasp pose adjustment, and 97% with loss-of-contact detection, achieving a submillimeter placement precision. Overall, this work demonstrates the feasibility and utility of integrating optical tactile sensors into the palm of a soft gripper and of applicability to various types of soft manipulators. The proposed grasping strategy has potential applications in areas such as fragile product processing and home assistance.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"24 22","pages":"38402-38416"},"PeriodicalIF":4.3,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645391","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}

Herin, it is proposed the NiO and Ag2 O metal oxide-doped Janus tin sulfide selenide (SnSSe) (MOS-SnSSe) monolayers as prospective sensing materials for detection of four typical decomposition gases, namely, HF, SO2, SOF2, and SO2F2, to provide an option for upgrading the gas-sensitive units. The results suggest that the NiO and Ag2 O dopants are more inclined to stick to the S-surface of intrinsic SnSSe monolayer. Furthermore, the Mulliken analysis reveals the function of carrier-migration bridge of the NiO and Ag2 O dopants in the gas-sensing reaction that encourages the bidirectional migration of charges between the gas species and the SnSSe surface. The change in energy band confirms the adjusted electronic performances of MOS-SnSSe monolayers upon adsorbing gases, and the density of state redistribution in such four gas systems verifies the chemisorption of HF, SO2, SOF2, and SO2F2 on NiO-SnSSe monolayer, the chemisorption of HF and SO2 on Ag2 O-SnSSe monolayer, and the physisorption of SOF2 and SO2F2 on Ag2 O-SnSSe monolayer. Furthermore, our outcome demonstrates that the NiO-SnSSe monolayer is a feasible candidate for an SO2 resistive sensor operating at 458 K, while Ag2 O-SnSSe monolayer can serve as both a work-function-type sensor for such four gas SPICEs and a scavenger for SO2. These discoveries in this research expose the admirable gas sensitivity potentiality of the SnSSe-based system and the special attribute of the Janus community, which we anticipate could motivate more cutting-edge research in the industry of gas sensing.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"24 22","pages":"37042-37052"},"PeriodicalIF":4.3,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636514","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 enable early detection and diagnosis of this disease, we have demonstrated an electrochemical immunosensor to detect the VP28 antigen, a key envelope protein of this virus. First, gold nanoparticles (AuNPs) were electrodeposited on the sensor’s carbon surface to enhance both its sensitivity and its capability to form a self-assembled monolayer (SAM). Subsequently, an SAM using 11-Mercaptoundecanoic acid was coated as an intermediary layer for immobilizing VP28 antibodies. The specific interaction of VP28 antigen-antibody, confirmed by Western Blot, impeded electrons transfer, leading to an increase in charge transfer resistance. Cyclic voltammetry (CV) was utilized to deposit AuNPs and combined with electrochemical impedance spectroscopy (EIS) to characterize the modification of the sensor’s electrode surface through changes in electric current and impedance. The scanning electron microscope (SEM) results showed that nanosized gold particles were uniformly dispersed on the carbon electrode surface.

Therefore, comprehensively characterizing the health state of IGBT and predicting its remaining useful life (RUL) using multiple signals poses a significant challenge. To address this challenge, a RUL prediction method for IGBT based on the deep fusion of nonlinear features from multisource data is proposed. First, the time-domain multifeatures of IGBT degradation data are constructed, and key features are selectively selected; then, dimensionality reduction is performed and these features are fused into health indicators (HIs) to characterize the health level. Second, the health of IGBT is effectively evaluated by unsupervised clustering without data labeling. Third, end-condition monitoring is refined to enable the identification of near-failure state.

The device employs a stepper motor to drive the polarizer, facilitating rapid and uniform rotation in front of the camera lens for efficient polarization imaging. The mechanical rotating components are fabricated using 3-D printing technology, which enhances its engineering application capabilities. To mitigate angle errors arising from the rotating mechanism, we propose an optimal robust measurement method based on Newton–Gauss iterations. The method utilizes the intensity images from four distinct polarization directions in consecutive compass output frames to estimate the rotation angle and skylight polarization information. Even in the presence of notable errors in the detected rotation angle, the calculated values of rotation angle, polarization angle, and polarization degree reliably converge to their actual values. To assess the performance of the compass, measurements of actual skylight polarization patterns were conducted and compared with polarizing camera measurements and the predictions based on single-scattering Rayleigh theory. The results affirm the compass’s high sensitivity to detecting polarized skylight. Shipborne experiments under optimal weather conditions illustrate that the compass attains a root mean square error (RMSE) of 3.0269° while independently orienting the dynamic heading angle, with an output frequency of 2 Hz. In practical applications, the compass proves capable of providing relatively accurate heading angle information, thus contributing to the advancement of mechanical rotating polarized imaging sensors in the field of polarized navigation.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"24 22","pages":"37809-37821"},"PeriodicalIF":4.3,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636319","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 article presents a novel characterization approach for THz metasurface that is resilient to environmental water vapor, enabling ultrahigh frequency selectivity and polarization sensitivity. The performance of the proposed method is demonstrated using a series of lithography-fabricated split-ring metasurface, theoretically designed to be evenly separated over the 0.6–1.0 THz range. A continuous wave THz frequency-domain spectroscopy system was employed for experimental characterization. Following sophisticated raw photocurrent data processing, ultrahigh frequency resolution (0.05 GHz) spectral characterization was achieved within the frequency range of 0.05 to 1.4 THz. The measured data exhibit linear correlation with the theoretical simulation results, and deviations of the resonance frequencies are less than 0.02 THz. By presenting the characterization results with and without water vapor exhibited in the THz pathway, we demonstrate the robustness of the proposed method in the ambient environment. Furthermore, we incorporated a sample rotating frame into the THz optical path to achieve polarization-sensitive measurements.

This mismatch inevitably introduces additional errors when calculating reprojection function, which in turn degrades the accuracy of simultaneous localization and mapping (SLAM). In this article, we propose a ground-aware decoupled optimized SLAM, called GDO-SLAM, which is essentially a pruning semantics-guided SLAM where a custom ground decoupling optimization module is introduced in the tracking and local mapping threads based on ORB-SLAM2. Essentially, the optimization module is a decoupling constraint that adds the weights of vertical observations of ground features and reduces the weights of horizontal observations in the reprojection error function. Specifically, we design a novel ground segmentation network that achieves an optimal balance between accuracy and real-time performance, and verify its ground category IoU of 98.6% on the urban landscape dataset. Extensive experiments on both the public KITTI dataset and our self-collected dataset demonstrate that our proposed ground-aware decoupling optimized SLAM (GDO-SLAM) outperforms the representative baseline ORB-SLAM2 in terms of translation and rotation accuracy by 7.5% and 8.3%, respectively.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"24 22","pages":"37218-37228"},"PeriodicalIF":4.3,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636229","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}
