In a training exercise, 50 firefighters swallowed the LifeMonitor capsule which is equipped with a thermometer and a transmitter. The pill transmits data to a device worn of the chest which also gathers heartbeat, respiration and skin temperature. This data is relayed in real-time allowing better management of heat-stress during firefighting. Victoria's Country Fire Authority trialled this new mechanism when they found that the standard measurement of temperature by the ear was an ineffective indication of heat-stress. The pill is expelled naturally after two days.
