Early detection is crucial to prevent long-term damage. Artificial intelligence (AI) with edge computing can significantly aid in the early diagnosis of keratoconus by reducing the computation time and increasing diagnostic accuracy. In this letter, we utilize a customized explainable Xception network for keratoconus detection. For this clinical infrared (IR) images are obtained from hospital under defined protocol. The IR images are preprocessed and pupil regions are extracted. The extracted regions are applied to XceptionNet, and integrated gradient-weighted class activation maps (GradCAM) are obtained. Experiment are performed to evaluate the performance of the network. Results show that the proposed approach is able to detect keratoconus images. The proposed approach yielded the average accuracy of 85%. GradCAM outcomes show that the trained model detected the regions similar to clinical interpretation. We assess the model's performance on an edge device, demonstrating its potential for real-time, on-site diagnostics. This application not only improves classification accuracy but also enhances interpretability, thereby assisting ophthalmologists in making informed decisions with greater confidence. Thus, the proposed architecture could be useful in clinical condition.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 1","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880280","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}

These improvements are achieved, first, by modifying the boundary conditions of the common resonant beam sensing elements to increase their responsiveness to axial forces and, second, by enhancing the efficiency of force-multiplier mechanisms to go beyond basic force-multiplication of the presently used lever structures. The effectiveness of these modifications is validated through simulations and experimental testing of fabricated test structures. We also demonstrate the utility of the approach through the analysis, design, and fabrication of several resonant accelerometers as prime candidates that benefit from these advancements. Experimental results demonstrate a 35% increase in device sensitivity compared to a baseline resonant accelerometer while offering a higher quality factor for the resonant beam elements, which can help improve the resolution of the sensor. The proposed approach does not require changes to microfabrication processes and can be utilized to improve the performance of various devices through simple structural modifications.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 1","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821277","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}

By deploying a single attacker with sufficiently large attack vectors in the network, the adversary can significantly degrade the performance of the estimator. Large attack vectors enhance the chance of attack detection. This letter aims to optimally design the measurement and channel attack vectors of a single attacker to maximally deviate the performance of the distributed estimation algorithm based on the maximum disturbance. A suboptimal joint measurement and channel attack design are provided using a Lagrange multipliers' method, in which the Lagrange multipliers are arbitrary and not obtained optimally. Subsequently, a suboptimal design for measurement-only and channel-only attacks is presented, with Lagrange multipliers derived mathematically. In fact, the false data injection (FDI) of a sensor has a profound effect on the performance of the distributed estimation in a sensor network. So, the action of even a single malicious sensor with deliberate attack design can degrade the true performance of the entire network. Simulation results demonstrate that these attack designs algorithms are more effective than random attack designs.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 1","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810623","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}

In the biomedical realm, humidity sensors play a vital role in point-of-care testing devices for detecting respiratory conditions, such as bronchitis, asthma, and pneumonia. This study presents a two-terminal metal–insulator–metal (MIM) device utilizing a composite of chicken egg albumin and tungsten trioxide (WO\u00003\u0000) as the active hygroscopic film, with aluminum and copper as the bottom and top electrodes, respectively. Albumin, a biocompatible and hydrophilic protein, efficiently absorbs moisture, while WO\u00003\u0000 nanoparticles, known for their excellent electrical conductivity, enhance the device's sensitivity to humidity changes. Experimental results demonstrate that increasing the WO\u00003\u0000 content in the composite film from 0% to 50% significantly improves the sensor's performance. Specifically, the maximum current response to humidity increased up to 15 times for pure albumin, 17.3 times for the albumin–WO\u00003\u0000 (25%) nanocomposite, and 21 times for the albumin–WO\u00003\u0000 (50%) nanocomposite, as the relative humidity varied from 20% to 95%.

This letter compares the sensitivity of two corona detection instruments in an unshielded laboratory. The sensitivity of an electrical detector according to IEC 60270 in combination with a measuring impedance and a coupling capacitor is compared with that of a digital single lens reflex (DSLR) camera. In addition, needle-to-plane and sphere-to-plane electrode geometries are studied under different types of high-voltage power supplies, i.e., 50 Hz ac, positive dc, and negative dc. Experimental results performed in an unshielded high-voltage laboratory show that although the DSLR camera is not a standard method for partial discharge (PD) detection, it has similar sensitivity to the conventional electrical method according to IEC 60270 in all cases analyzed, and that the digital camera behaves much better in pulseless glow corona mode.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"8 12","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798032","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}
