This letter presents an aerosol-jet-printed zinc oxide (ZnO) nanowire UV photodetector fabricated on a Si/SiO2 substrate using printed interdigitated Ag electrodes and a ZnO nanowire sensing layer. The device exhibits strong wavelength- and intensity-dependent photoresponse under 340 and 375 nm UV illumination at a 1 V bias. At the same irradiance of 60 <italic>μW·cm−2, the photocurrent reached ∼0.9 mA at 340 nm and ∼0.11 mA at 375 nm, corresponding to responsivities of 31.71 and 3.67 A/W, respectively. Transient measurements reveal pronounced persistent photoconductivity and strong dependence of recovery behavior on illumination conditions. In addition, thermal cycling experiments and a 10-nm Al2O3 atomic layer deposition encapsulation layer were used to investigate the role of oxygen-related surface processes in carrier transport and recovery dynamics. These results provide insight into the transient photoresponse mechanisms of ZnO nanowire UV photodetectors and the influence of surface interactions on device behavior.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 8","pages":"3504704-3504704"},"PeriodicalIF":2.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148628257","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}

It investigates whether multiple low-quality cameras can achieve performance comparable to high-quality systems. Sensor properties, including spatial resolution, noise behavior, and dynamic range, are analyzed using a reproducible evaluation procedure. A bird’s-eye-view detection and fusion pipeline enables direct attribution of performance variations to hardware characteristics. Experiments under controlled illumination (sunny, cloudy, and nighttime) show that detection performance does not increase monotonically with resolution, achieving best results at intermediate resolutions (mIoU up to 0.9156), while both lower (0.8054) and higher resolutions reduce performance. High-quality sensors provide higher localization accuracy and robustness, particularly under low-light conditions. Fusion achieves intersection-over-union values up to 0.83, with sensor quality directly affecting accuracy and variance. Multiview fusion can partially compensate for lower sensor quality, though with increased noise sensitivity. The proposed methodology enables objective comparison and selection of camera systems for robust parking monitoring.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 8","pages":"5504904-5504904"},"PeriodicalIF":2.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148628277","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, they are still in its infancy with ample room for the exploration of novel materials that enable the generation of HMR. This work explores the utilization of fluorinated tin oxide (SnO2:F), hafnium dioxide (HfO2), and tungsten trioxide (WO3) as external coatings for HMR generation using a planar waveguide configuration (24 mm x 32 mm coverslips). Basic HMR structure consisted of a combination of DC and RF sputtered coatings of an intermediate Au layer and a metal oxide external layer, respectively. The sensors’ spectral responses were measured over a refractive index (RI) range spanning from air (≈1.0) to 1.45, covering relevant analytes in gas and liquid sensing. HMR sensors exhibited distinct resonance features that shift systematically with increasing RI, enabling accurate label-free refractometry. The obtained sensitivity, figure of merit, and linearity are compared across the three devices, highlighting the influence of the hyperbolic metamaterial design on the sensing performance. Obtained results demonstrate that HMR-based sensors can provide compact and versatile platforms for RI detection, with enormous potential for integration into lab-on-a-chip systems.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 8","pages":"3504404-3504404"},"PeriodicalIF":2.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148626391","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 this work, these strengths are exploited to address a key challenge in dielectrophoresis (DEP)-based nanowire (NW) assembly, namely, the need for microelectrodes with gaps closely matched to NW length for effective trapping. By optimizing nozzle geometry and printing parameters, interdigitated silver nanoparticle microelectrodes with a 10 µm gap were directly printed onto flexible polyimide substrates, matched to the 15–20 µm length of ZnO NWs. Optimized DEP conditions of 24 Vpp at 1 MHz enabled deterministic NW alignment across the electrode gaps. The resulting flexible UV photodetectors exhibited a clear photoresponse at 365 nm, with a responsivity of 31 AW−1 at 8 V bias and response and recovery times of 18 and 82 s, respectively. Through these proof of concept devices, this work demonstrates that high-resolution DIW-printed microelectrodes provide a scalable, resource-efficient, and accessible platform for DEP-based NW integration, opening a practical pathway toward low-cost flexible electronic devices.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 8","pages":"3504004-3504004"},"PeriodicalIF":2.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148627386","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}

Despite the utility of tactile information for many applications, piezoelectric tactile sensors have yet to be widely deployed in identifying slip and other events from the tactile data stream. In this letter, we present a learning-based method to detect slip onset and contact events using flexible piezoelectric sensors. Two approaches were implemented: First, the extraction of frequency domain features to train a multilayer perceptron; Second, developing a 1D-convolutional neural network (1D-CNN) using raw tactile signals. Furthermore, an analysis was conducted to evaluate the impact of temporal window size on the recognition performance and real-time feasibility. Results demonstrated that the optimal configuration was achieved using the 1D-CNN with a 25 ms temporal window while achieving a recognition accuracy of 95.5% and an end-to-end latency of 41 ms. These findings highlight that piezoelectric sensing technology, combined with data-driven learning, is suitable for implementing an autonomous control for robot manipulation.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 8","pages":"5504804-5504804"},"PeriodicalIF":2.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11611704","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148627577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its nonlinear and nonstationary nature, EEG signal-based stroke and TBI analysis is complicated. Therefore, an advanced signal decomposition technique-based classification framework is essential for extracting significant features and improving detection accuracy. This letter presents a novel multiclass classification framework for decoding neurological disorders using the multichannel EEG sensor data. The proposed framework utilizes Fourier–Bessel series expansion-based empirical wavelet transform (EWT) to extract oscillatory patterns related to these neurological signals of stroke and TBI. To evaluate the proposed framework, we have developed two additional classification frameworks using empirical mode decomposition and EWT to enable a direct comparison. The proposed framework is evaluated using two performance metrics, time-frequency representation and classification accuracy, and it is also validated using receiver operating characteristic curves. This study presents the formulation of hand crafted features, including spectral entropy, energy of the Hilbert spectrum, mean of instantaneous amplitude, and variance of instantaneous amplitude. Experimentally, the proposed framework outperforms state-of-the-art methods and shows potential as a reliable preclinical tool for neurological disorder detection.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"10 8","pages":"7003704-7003704"},"PeriodicalIF":2.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148626159","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}
