Monitoring physiological variables of mining workers at high altitude

Miners working at high altitude must handle extreme climatic and physiological hazards without specialized medical supervision. For this reason, the mining industry is constantly looking for improvements to existing Occupational Safety and Health (OSH and environmental variables: ambient temperature and relative humidity. The non-invasive sensors of the proposed system are embedded all throughout a T-shirt (first layer of protecting clothing) to achieve a functional device and maximum comfort for the users. The device is able to continuously calculate heart and respiration rate, and establish a wireless data transmission to a central monitoring station.
