Skin is the interface between our body and the environment. Its unique properties and sensing capabilities allow us to perceive the world around us. Information about shape, texture, stiffness, temperature, and pain conveyed by touch facilitates our ability to perform tasks and manipulate objects dexterously [1]. Adding sensory feedback in prosthetic limbs will enable users to interact with the environment naturally and effectively, instead of relying solely on visual cues. Tactile sensing technologies, in the form of highly dense sensor arrays and neuromorphic encoding circuits coupled to a neuromodulator, are poised to revolutionize prosthetic devices. On the other hand, such a sensing and signal computing system architecture can provide a general platform for seamless and minimally invasive wearable and implantable devices (Fig. 12.4.1).

A wireless sensor Network (WSN) is organized of multiple nodes in a large area distributed randomly, each node was sending information at same time that led to conflict among them, the goal is to resolve the emerging complex conflict in WSN through the utilization of Procedure for electing the own cluster. This required need to optimize the own cluster election and extending life cycle of network. In this paper a support vector machine (SVM) based on clustering algorithm is proposed during election process. The WSN has remaining energy of node, distance from base station and probability of node serving as own cluster. The own cluster is optimized by SVM algorithm to adaptive inertia weight, it considers nodes within the communication range are regarded as its cluster members such number of own clusters selected to satisfies the optimal number of own clusters, and thereby further improving energy efficiency of the network. The simulation results show that the SVM algorithm is more efficient when compared to other algorithms, also the algorithm proven that period of network stability in balancing consuming energy is more effective and more extending the network life cycle.

This paper presents an approach to target detection in automotive radar systems, where the highly dynamic nature of the sensor platform and environment, along with challenges such as hardware cost and installation constraints, necessitates a general sensor configuration that integrates widely separated, colocated MIMO, and distributed aperture radar (DAR). A joint Doppler processing and MIMO transmit demodulation technique is proposed, utilizing arbitrary DDM, TDM, or BPM precoding matrices with a lower-dimensional antenna steering matrix as the detection input. The signal model incorporates environmental information, such as the cell under test (CUT) range and line-of-sight regions, to enhance detection performance. A distributed Generalized Likelihood Ratio Test (GLRT) detector is derived using secondary data with CFAR property, and the robustness of the proposed detectors is evaluated under mismatch conditions using mesa plots. Simulation results demonstrate the effectiveness of the proposed approach, evaluated using key performance metrics such as probability of detection, probability of false alarm.
In this paper, we propose a combination of Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) to create a hybrid optimization technique which meets k-coverage criteria in Wireless sensor Network (WSN) and In...

The rapid advancement in retail technology has necessitated the development of systems that can adapt to dynamic customer behaviours and optimize pricing strategies in real time. This paper presents a smart retail system that integrates edge computing and IoT automation to address these challenges effectively. The system utilises YOLOv8 for real-time crowd counting, with camera sensors deployed around product shelves to monitor customer interactions. IoT devices, including smart shelves and QR codes, facilitate real-time data communication and enhance customer engagement. Edge computing processes this data locally to enable immediate adjustments in pricing and inventory management, minimizing latency and improving responsiveness. The integration of these technologies aims to optimize operational efficiency, enhance the shopping experience, and provide personalized promotions based on real-time crowd density and sales data.

LiDAR sensors play a crucial role in various applications such as autonomous vehicles, robotics, and environmental monitoring. The performance of these sensors significantly impacts the quality and accuracy of 3D mapping in real-world scenarios. While traditional evaluations often rely solely on specifications, a more comprehensive comparison can be made with the sensors' performance in practical mapping contexts. This paper addresses this need by proposing new LiDAR comparison criteria and conducting an extensive comparison of three LiDAR sensors: Livox Mid-360, Ouster OS1, and Velodyne Puck. The new proposed comparison criteria evaluates different sensors' behaviours in diverse environments with no ground truth, particularly by computing and comparing with the proposed reference maps. In each environment, for each sensor, a point cloud 3D map is obtained through a Simultaneous Localization and Mapping (SLAM) method, where the comparison criteria are applied.

Against the backdrop of the rapid development of unmanned aerial vehicle (UAV) technology, onboard visual navigation systems have become the core support technology for achieving precise positioning and efficient map construction of UAVs. This paper deeply explores the key technologies of sensor data spatiotemporal synchronization in onboard visual navigation systems, aiming to solve the synchronization issues in multi-sensor data fusion in variable environments, and enhance the navigation accuracy and reliability of UAVs. The research covers both spatial and temporal synchronization dimensions, with a focus on the technical implementation of Visual-Inertial Odometry (VIO). For spatial synchronization, a target-based method is proposed to construct an error equation for solving the extrinsic parameters between the camera and the Inertial Measurement Unit (IMU), achieving precise alignment of sensor coordinate systems through the identification and matching of visual target feature points. In terms of temporal synchronization, considering the data frequency differences between the camera and IMU, this paper designs a time alignment strategy that realizes efficient temporal alignment of data through data buffering and timestamp matching. Additionally, the initialization and local sliding window optimization process of the Visual-Inertial Odometry are detailed, achieving high-precision fusion of visual and inertial data through feature extraction, optical flow tracking, and motion structure recovery. Experimental results show that the methods proposed in this paper can technically provide strong support for the autonomous flight of UAVs, effectively improving the navigation performance of UAVs in complex environments, and enhancing the robustness of the system.
