Abstract: This paper introduces the Wartech Jacket, an innovative IoT- enabled wearable system designed to enhance soldier safety through comprehensive real-time health and environmental monitoring during military operations. The system combines multiple biosensors and environmental monitoring capabilities to track vital signs—including heart rate, body temperature, and GPS location—while detecting hazardous gases and smoke in hostile environments. Built around the ESP32 microcontroller, the system establishes robust dual-channel communication via WiFi and GSM networks, ensuring connectivity even when a single channel becomes unavailable. When abnormal physiological conditions or environmental hazards are detected, the system automatically triggers emergency alerts that are routed to military command centers and medical facilities. Rigorous testing has validated the system’s core capabilities: reliable sensor integration, a 99.2% packet delivery success rate for critical alerts, and emergency response generation within 0.8 seconds. Beyond laboratory validation, field testing confirms that this system enables meaningful enhancements to soldier safety through continuous health monitoring, rapid emergency response, and precise location tracking in challenging environments. The prototype operates for 9.2 hours on a single battery charge while maintaining measurement accuracy within medical standards. Finally, the modular design allows straightforward integration of additional sensors and machine learning algorithms as soldier protection capabilities evolve.
