Wearable electronic textiles (e-textiles) have gained significant attention in recent years, particularly for long-term biopotential signal monitoring. In this study, we present two wearable electrode designs—a headband and a neckband—tailored specifically for electrocardiogram (ECG) signal acquisition from behind the ear and around the neck regions. These designs were benchmarked against standard Ag/AgCl electrodes over 30 voluntary participants and demonstrated maximum correlation values as high as 98% and above for both designs, with an average correlation of 90.1% and 91.9% for the headband and neckband, respectively. A detailed investigation of six different electrode placements on the neck was also conducted to determine the optimal positions for recording ECG signals. The robustness of the designs was evaluated through 40-min ECG recordings and under various intense movement conditions. Furthermore, to advance the development of sustainable and reliable wearable e-textile systems, we evaluated the real-life performance of textile electrodes reduced using two different agents: L-ascorbic acid, an eco-friendly, bio-based compound, and sodium borohydride, a commonly used but toxic chemical. While both agents are already known to effectively reduce graphene oxide (GO), the primary objective was to comparatively assess the functional performance of the resulting electrodes under real-world conditions, specifically in scenarios relevant to wearable ECG monitoring applications. The reported results enhance the understanding of the efficiency and performance of the developed wearable e-textile designs for biopotential signal monitoring.
近年来,可穿戴电子纺织品(e-纺织品)获得了极大的关注,特别是长期生物电位信号监测。在这项研究中,我们提出了两种可穿戴电极设计——一种头带和一种颈带,专门用于从耳后和颈部周围采集心电图信号。这些设计与30多名自愿参与者的标准Ag/AgCl电极进行基准测试,两种设计的最大相关值均高达98%以上,头带和颈带的平均相关性分别为90.1%和91.9%。研究人员还对脖子上6种不同的电极放置位置进行了详细研究,以确定记录ECG信号的最佳位置。通过40分钟的心电图记录和各种剧烈运动条件来评估设计的稳健性。此外,为了促进可持续和可靠的可穿戴电子纺织品系统的发展,我们评估了使用两种不同的剂减少的纺织品电极的实际性能:l-抗坏血酸,一种环保的生物基化合物,和硼氢化钠,一种常用但有毒的化学物质。虽然已知这两种试剂都可以有效地减少氧化石墨烯(GO),但主要目的是比较评估在现实条件下产生的电极的功能性能,特别是在与可穿戴ECG监测应用相关的场景中。报告的结果增强了对开发的可穿戴电子纺织品设计用于生物电位信号监测的效率和性能的理解。

This work presents the design and evaluation of a low-power data logger for multisensor data acquisition, intended for deployment in urban sewage infrastructure. The system integrates Internet of Things (IoT) communication capabilities to interface with a smart city’s centralized data platform. Two low-power wide area (LPWA) communication technologies—narrowband IoT (NB-IoT) and Sigfox/long range (LoRa)—are analyzed and compared in terms of power consumption, hardware cost, and data transmission performance. The results offer practical guidance for selecting the most suitable communication protocol based on application-specific constraints, such as message frequency, energy availability, and bidirectional communication requirements. Sigfox is selected for occasional alert messages, while NB-IoT is used for the daily bulk transmission of measurements.

Distinguishing between indoor and outdoor environments is crucial for various location-based applications, including navigation tools and context-aware services. We present an innovative and highly efficient approach that combines air quality sensors with machine learning techniques to achieve this distinction. Extensive experiments across diverse settings—buildings and vehicles—and data from two cities, Helsinki, Finland, and Milan, Italy, with distinct environmental characteristics, demonstrate significant performance improvements. Specifically, our method achieves over 90% accuracy, a 30% increase compared to approaches relying solely on location information. This work highlights a novel application of air quality data and provides an enhanced methodology for accurately distinguishing indoor and outdoor spaces.

Multiplatform specific emitter identification (SEI) shows performance degradation due to the significant distributional discrepancies in heterogeneous features. To address this challenge, we propose a graph convolutional deep residual network (ResNet) for classification. First, a platform–target association matrix is constructed based on the statistical features of radar data. Tag features are then implicitly modeled via tag embedding, and deep signal features are extracted using a deep residual convolutional module. Subsequently, the data and tag features are fused through attention-weighted feature splicing. To fully exploit tag dependencies, the graph convolutional network (GCN) is enhanced to accept the spliced features as input, enabling the generation of feature maps that yield learnable classifiers. The extracted features and generated classifiers are integrated to produce the final classification results. Experiments on real-world datasets reveal that the proposed method achieves the dynamic fusion and efficient classification of cross-platform multitag features. Compared to traditional independent multiclassification approaches, it improves accuracy and computational efficiency by 17% and 9.3%, respectively. Moreover, the integration of implicit tag modeling and feature splicing contributes an additional 8% gain in accuracy, fully meeting the practical application requirements of real-world scenarios.
多平台特定发射器识别(SEI)由于异构特征的显著分布差异而导致性能下降。为了解决这一挑战,我们提出了一种用于分类的图卷积深度残差网络(ResNet)。首先,基于雷达数据的统计特征,构建平台-目标关联矩阵;然后通过标签嵌入隐式建模标签特征,并使用深度残差卷积模块提取深度信号特征。随后,通过关注加权特征拼接将数据和标签特征融合在一起。为了充分利用标签依赖性,对图卷积网络(GCN)进行了增强,使其能够接受拼接特征作为输入,从而生成可学习分类器的特征映射。将提取的特征和生成的分类器相结合,产生最终的分类结果。在实际数据集上的实验表明,该方法实现了跨平台多标签特征的动态融合和高效分类。与传统的独立多分类方法相比,准确率和计算效率分别提高17%和9.3%。此外,将隐式标签建模和特征拼接相结合,精度提高8%,完全满足真实场景的实际应用需求。

Sleep apnea is a common sleep-related condition defined by repeated pauses in respiration during sleep, which increases the risk of severe health complications. Polysomnography (PSG) is the diagnostic gold standard; however, its limited accessibility and poor suitability for long-term monitoring necessitate alternative home-based techniques. This study introduces an unconstrained sleep apnea detection system based on a convolutional vision transformer (Conv-ViT) with personalization via low-rank adaptation (LoRA). Data were collected from 121 participants who underwent PSG using a polyvinylidene fluoride (PVDF) sensor placed underneath a mattress topper to capture unconstrained signals. The Conv-ViT model combines a convolutional neural network (CNN) for localized features extraction with ViT for global representation learning and was fine-tuned on PVDF signals via transfer learning from PSG-derived airflow data. For personalization, LoRA tuning was applied to reflect the individual physiological variability. The evaluation results showed that Conv-ViT outperformed standalone CNN and ViT models, achieving Cohen’s kappa (KAPPA) of 0.736 and accuracy of 0.903 on a test dataset of 61 participants. Personalization with LoRA improved the performance, increasing the mean participant-level KAPPA from 0.674 to 0.728 and the event-level KAPPA from 0.736 to 0.763. Furthermore, the model effectively classified apnea severity, achieving a KAPPA of 0.73 and an average accuracy of 0.93. These findings demonstrate that an end-to-end Conv-ViT model using unconstrained PVDF signals can reliably detect sleep apnea and assess its severity, offering scalable, long-term, and individualized home-based sleep apnea monitoring.
睡眠呼吸暂停是一种常见的睡眠相关疾病,由睡眠期间呼吸反复暂停所定义,这增加了严重健康并发症的风险。多导睡眠图(PSG)是诊断的金标准;然而,其有限的可及性和长期监测的不适宜性需要替代的基于家庭的技术。本研究介绍一种基于低阶自适应(LoRA)个性化的卷积视觉转换器(convv - vit)的无约束睡眠呼吸暂停检测系统。数据来自121名参与者,他们使用放置在床垫顶部下方的聚偏氟乙烯(PVDF)传感器进行PSG,以捕获无约束信号。卷积-ViT模型结合了卷积神经网络(CNN)的局部特征提取和卷积神经网络(ViT)的全局表征学习,并通过从psg导出的气流数据进行迁移学习,对PVDF信号进行微调。在个性化方面,采用LoRA调整来反映个体的生理变异性。评估结果表明,convv -ViT模型优于独立的CNN和ViT模型,在61个参与者的测试数据集上达到了0.736的Cohen kappa (kappa)和0.903的准确率。使用LoRA的个性化改进了性能,将参与者水平的平均KAPPA从0.674提高到0.728,将事件水平的KAPPA从0.736提高到0.763。此外,该模型有效地对呼吸暂停严重程度进行分类,KAPPA为0.73,平均准确率为0.93。这些发现表明,使用无约束PVDF信号的端到端convv - vit模型可以可靠地检测睡眠呼吸暂停并评估其严重程度,提供可扩展的、长期的、个性化的家庭睡眠呼吸暂停监测。

This article proposes a physical-neural adaptive super-twisting momentum observer (ASTMO) to estimate interaction forces between a robot manipulator and uncertain environments. The proposed method reduces reliance on force/torque sensors while maintaining high estimation accuracy. Concretely, traditional dynamic modeling and identification methods often encounter challenges like unmodeled dynamics and parametric uncertainties, which may lead to significant modeling errors and adversely impact the accuracy of force estimation. To overcome these limitations, a hybrid model integrating physical dynamics with neural network (NN) corrections is proposed, introducing a unified framework that concurrently leverages model-based and data-driven strategies. The dynamic model is initially developed using the Newton–Euler method, followed by parameter identification to establish the physical model (PM). A backpropagation (BP) NN is then utilized to capture and correct residual model errors. Utilizing such a hybrid model, an ASTMO is constructed for external torque estimation. This effectively attenuates the chattering effect commonly associated with sliding mode control and improves estimation precision under uncertain operating conditions. Experimental validation on a six-degree-of-freedom (6-DoF) manipulator using a Beckhoff controller demonstrates the effectiveness in external torque estimation without a force/torque sensor.
本文提出了一种物理-神经自适应超扭转动量观测器(ASTMO)来估计机器人操纵臂与不确定环境之间的相互作用力。该方法减少了对力/扭矩传感器的依赖,同时保持了较高的估计精度。具体而言,传统的动力学建模和辨识方法往往会遇到未建模动力学和参数不确定性等挑战,从而导致建模误差显著,影响力估计的准确性。为了克服这些限制,提出了一种将物理动力学与神经网络(NN)校正相结合的混合模型,引入了一个统一的框架,同时利用基于模型和数据驱动的策略。首先采用牛顿-欧拉法建立动力学模型,然后通过参数辨识建立物理模型(PM)。然后利用反向传播(BP)神经网络捕获和修正残差模型误差。利用该混合模型,构造了用于外转矩估计的ASTMO。这有效地减弱了滑模控制中常见的抖振效应,提高了不确定工况下的估计精度。在使用倍福控制器的六自由度(6-DoF)机械臂上进行了实验验证,证明了在没有力/扭矩传感器的情况下进行外部扭矩估计的有效性。

Continuous object tracking in the Internet of Things (IoT)-enabled wireless sensor networks (WSNs) requires fast, energy-efficient boundary detection, especially for dynamic phenomena such as toxic gas leakage or wildfire spread. However, existing approaches often rely on cloudcentric processing, resulting in high transmission delays and excessive energy consumption due to large-scale node activation. This article proposes boundary detection of continuous objects (BDCO), a fog-assisted scheme that reduces communication overhead and improves boundary accuracy. BDCO organizes the network into grid-based clusters where the cluster head (CH) filters anomalous data using a selective aggregation mechanism and forwards only relevant boundary-related information to the fog node (FN). The FN then applies a convex hull-based boundary estimation model, enabling precise boundary formulation while minimizing node activation. The proposed scheme is implemented in NS-2.35 and demonstrates substantial improvements in energy consumption (3.00E+06), service delay (22 ms), end-to-end delay (33 ms), packet loss ratio (3.0), and boundary accuracy (0.85) compared to existing approaches. Overall, the BDCO scheme provides a more energy-efficient and delay-aware solution for real-time BDCO in an IoT-enabled WSN environment.
在支持物联网(IoT)的无线传感器网络(wsn)中,持续目标跟踪需要快速、节能的边界检测,特别是对于有毒气体泄漏或野火蔓延等动态现象。然而,现有的方法往往依赖于以云为中心的处理,导致高传输延迟和由于大规模节点激活而导致的过度能耗。本文提出了连续目标的边界检测(BDCO),这是一种雾辅助方案,可以减少通信开销并提高边界精度。BDCO将网络组织成基于网格的簇,其中簇头(CH)使用选择性聚合机制过滤异常数据,并仅将相关的边界相关信息转发给雾节点(FN)。FN然后应用基于凸壳的边界估计模型,在最小化节点激活的同时实现精确的边界公式。所提出的方案在NS-2.35中实现,与现有方法相比,在能耗(3.00E+06)、服务延迟(22 ms)、端到端延迟(33 ms)、丢包率(3.0)和边界精度(0.85)方面有了实质性的改进。总体而言,BDCO方案为支持物联网的WSN环境中的实时BDCO提供了更节能和延迟感知的解决方案。
