Wireless Passive Monitoring of Electrocardiogram in Firefighters

摘要

Firefighters, although equipped with specialized protective garment, are in danger not only during but also after incidents. This calls for a dire need to monitor firefighters' survival signs such as body temperature and heart rate. Here, we develop a novel electrocardiogram (ECG) monitoring system consisting of non-contact electrode (NCE) bio-potential sensors and an inductive link for both wireless power transfer (WPT) and data communication. Various experiments were thoroughly conducted to characterize the efficiency of WPT and ECG signal quality in practical scenarios. Our method can also be implemented to provide monitoring of other physiological parameters, such as motion and body temperature, thus holding promise to promote safety of firemen.
