The CAPSARII Approach to Cyber-Secure Wearable, Ultra-Low-Power Networked Sensors for Soldier Health Monitoring

Luciano Bozzi, Christian Celidonio, Umberto Nuzzi, Massimo Biagini, Stefano Cherubin, Asbjørn Djupdal, Tor Andre Haugdahl, Andrea Aliverti, Alessandra Angelucci, Giovanni Agosta, Gerardo Pelosi, Paolo Belluco, Samuele Polistina, Riccardo Volpi, Luigi Malagò, Michael Schneider, Florian Wieczorek, Xabier Eguiluz

TL;DR

CASPARII tackles the problem of safeguarding soldiers and improving battlefield decision-making by deploying an Internet of Battlefield Things (IoBT) wearable system that collects physiological, movement, and environmental data. The approach integrates edge AI, cloud analytics, smart textiles, and secure, energy-efficient hardware (RISC-V, PIM) to deliver real-time tactical insights while preserving battery life and data confidentiality. Key contributions include an end-to-end data flow (edge to cloud), federated/meta-learning for cross-user adaptation, and co-design of ultra-low-power AI accelerators with security-focused identity and authentication. The work aims to transform military operations by providing data-driven, privacy-preserving decision support across EU partners, with practical impact on pilot fatigue management and performance in harsh environments.

Abstract

The European Defence Agency's revised Capability Development Plan (CDP) identifies as a priority improving ground combat capabilities by enhancing soldiers' equipment for better protection. The CAPSARII project proposes in innovative wearable system and Internet of Battlefield Things (IoBT) framework to monitor soldiers' physiological and psychological status, aiding tactical decisions and medical support. The CAPSARII system will enhance situational awareness and operational effectiveness by monitoring physiological, movement and environmental parameters, providing real-time tactical decision support through AI models deployed on edge nodes and enable data analysis and comparative studies via cloud-based analytics. CAPSARII also aims at improving usability through smart textile integration, longer battery life, reducing energy consumption through software and hardware optimizations, and address security concerns with efficient encryption and strong authentication methods. This innovative approach aims to transform military operations by providing a robust, data-driven decision support tool.
