Assessing Non-Intrusive Wearable Devices for Tracking Core Body Temperature in Hot Working Conditions

Heat-related illness is a growing concern for workers in temperate climates as rising temperatures and heatwaves put them at risk of exertional heat stroke. Monitoring biometrics that predict stroke, such core temperature, increasingly important. To monitor biometrics, wearable sensing technologies have been proposed an alternative to the ingestible telemetric pill. However, limited studies validated accuracy these sensors different temperature conditions. Therefore, this study aims assess validity devices placed on areas body measuring (CT) during repetitive physical activity high Ten male participants performed dumbbell curling exercises 33 °C roughly 50% relative humidity, data from pill (the criterion standard) were compared two sensors–Slate Safety Zephyr. Results showed Slate [Bias (Precision) = 0.20 (0.35) °C) Zephyr −0.03 °C] recorded bias precision within acceptable limits. The correlation analysis are suitable real-time monitoring individual’s level stress temperatures. there was proportional with CT devices, meaning reported values consistently deviated true values. results contribute ongoing discussion most appropriate methods provide valuable information practitioners working field.
