ARMOR consists of a heart rate sensor, the ARMOR device and ARMOR app. From the heart rate data, the core body temperature of each soldier is estimated and this information is sent to the app. The app provides an overview with details of all participants. For each participant, the current estimated core body temperature is displayed, as well as the physiological strain index (PSI). The PSI is a rating of the relative heat strain on a scale of 1 to 12.As soon as the heat strain of a participant is too high, the app will sound an alarm. The supervisor can then intervene immediately and initiate actions according to a defined protocol.
The device helps to identify the first indications that cause heat stress and serves as an incentive for a medical check to prevent this.
The ARMOR Heat Monitor measures the heart rate with a standard Bluetooth sensor. The data is processed with the patented ECTemp algorithm, resulting in an accurate estimate of core body temperature. This integrated ECTemp algorithm used to estimate core body temperature is developed by the United States Army Research Division (USARIEM) and has been extensively tested for accuracy. It is used for ARMOR Heat Monitor under license.
The ARMOR app displays the current estimated core body temperature is displayed, as well as the PSI. The app identifies the risks to the participants using a color scheme (green, orange, red) that can be customized by the supervisor.
The ARMOR heat monitor has been tested in various training situations by the Dutch army. Now, more than 1,000 ARMOR Heat Monitor systems are in use at Defense training centers in the Netherlands.
