A Real Time Multi-Sensor Wearable for Early Hypothermia and Heat Strain Detection

Overview

Extreme temperatures pose significant threats to human health. Each year, millions of deaths are linked to cold-related conditions, while extreme heat causes around 489,000 deaths. Early symptoms, which may resemble normal responses to cold or heat, are often not recognized until the conditions become severe. High-risk groups include homeless individuals, infants, and older adults. Detecting hypothermia or heat strain early is difficult because these conditions depend on core body temperature rather than skin temperature. However, real-time devices for measuring core temperature are invasive, expensive, and inaccessible to most people. To address this, I invented a low-cost wearable device that uses a heart-rate sensor, thermistor, and accelerometer. It can estimate core temperature with personalized AI analysis and provide early warnings for both cold and heat risks. With a prototype cost of only $28 and the potential for future cloud-based AI integration, this device makes early detection more affordable and accessible.
