Research of Detection System for the Heatstroke Which Caused by Wearing Protective-Clothes, Based on Heartbeat Information Using Clothing-Type Wearable Sensors

This report is the overview of the research by Chemical School, Japan Ground Self-Defense Force (JGSDF), which analyzed the heartbeat data obtained using wearable sensors. The participants were the member of the Chemical unit of JGSDF, all the participants were male. Training wearing protective-clothes which protects a body from chemical agents in high temperature environment gives a very high heat stress to body. It is very important to have the safety measures for reducing the risk of member’s heatstroke. By being exposed to high temperature environment and high humidity in protective-clothes, member’s core body temperature rises and it read to dangerous state of body which causes heatstroke. However, even if member’s becomes dangerous physical condition, they have to continue working for their duties. It is difficult to avoid onset of serious heatstroke by member’s own senses. So, the system which monitors each member’s performance and physical condition by administrator is required. Therefore, we try to develop the system that detects signs of heatstroke by real-time monitoring. In this research, I used the clothing-type wearable sensors which combined the small heart rate sensor. We measured heartbeat of members wearing protective-clothes during actual training and attempted to evaluate heat stress. We describe the heatstroke detection system based on heartbeat information which we have challenged.
