Journal of Sensor and Actuator Networks, Volume 14, Issue 1

2025 February - 21 articles

Cover Story: While wireless solutions usually dominate body sensor networks, wired methods excel where dense sensor/actuator deployments, low latency, and high reliability are needed. Despite decades of wired communication advancements, wearable applications have lagged behind, burdened by complex wiring and communication overhead. We address this gap by introducing a novel serial protocol with group addressing that cuts overhead by up to 50%, as well as demonstrating its use in an interactive jacket prototype over a semiduplex UART. Using only a three-wire bus for power and communication, the jacket supports nine sensors/actuators, achieving a 2.27 ms feedback delay and a 435.4 Hz frame rate, matching top-performing multi-node wearables while maintaining flexible, efficient wiring.
