Special Issue Information

Dear Colleagues,

The convergence of Edge Artificial Intelligence (Edge AI) and wearable sensor technologies is transforming personalized healthcare, human–machine interaction, and ubiquitous sensing. Unlike cloud-based systems, Edge AI-enabled wearables can process data locally, reducing latency, preserving privacy, and enabling real-time adaptive responses. This Special Issue invites contributions exploring next-generation intelligent wearables powered by embedded AI algorithms, neuromorphic computing, and ultra-low-power architectures. Submissions may focus on adaptive signal processing, context-aware intelligence, and secure integration into IoT frameworks. The issue also welcomes research on bio-integrated electronics and intelligent devices that merge advanced electronics with computational intelligence. Bringing together experts from electronics, computing, and AI, this Special Issue highlights how Edge AI transforms wearable platforms such as smartwatches, wristbands, glasses, necklaces, head caps, and other innovative devices into intelligent, adaptive, and resilient companions, advancing the mission of Sensors to promote innovation across connected sensing ecosystems.

Scope & Topics

Submissions encouraged include, but are not limited to, the following areas:

  • Edge AI architectures for wearable sensors.
  • Machine learning and adaptive signal processing for physiological, environmental, or activity monitoring.
  • Flexible and adaptive electronic systems for wearables.
  • Secure and privacy-aware wearable IoT frameworks.
  • Neuromorphic and bio-inspired computing at the edge.
  • Real-time analytics for health, sports, and environmental applications.
  • Design, prototyping, and scalability of wearable platforms.

Event-based sensors provide sparse, motion-centric measurements that can reduce data bandwidth and enable always-on perception on resource-constrained edge devices. This paper presents an event-based machine vision framework for smart-home AIoT that couples a Dynamic Vision Sensor (DVS) with compute-efficient algorithms for (i) human/object detection, (ii) 2D human pose estimation, (iii) hand posture recognition for human–machine interfaces. The main methodological contributions are timestamp-based, polarity-agnostic recency encoding that preserves moving-edge structure while suppressing static background, and task-specific network optimizations (architectural reduction and mixed-bit quantization) tailored to sparse event images. With a fixed downstream network, the recency encoding improves action recognition accuracy over temporal accumulation (0.908 vs. 0.896). In a 24 h indoor monitoring experiment (640 × 480), the raw DVS stream is about 30× smaller than conventional CMOS video and remains about 5× smaller after standard compression. For human detection, the optimized event processing reduces computation from 5.8 G to 81 M FLOPs and runtime from 172 ms to 15 ms (more than 11× speed-up). For pose estimation, a pruned HRNet reduces model size from 127 MB to 19 MB and inference time from 70 ms to 6 ms on an NVIDIA Titan X while maintaining a comparable accuracy (mAP from 0.95 to 0.94) on MS COCO 2017 using synthetic event streams generated by an event simulator. For hand posture recognition, a compact CNN achieves 99.19% recall and 0.0926% FAR with 14.31 ms latency on a single i5-4590 CPU core using 10-frame sequence voting. These results indicate that event-based sensing combined with lightweight inference is a practical approach to privacy-friendly, real-time perception under strict edge constraints. Full article
