Bio-OS Data Input: sensor strap

The Bio-OS strap is a modification based on the Polar Wireless ECG System. In addition to its existing electrodes, on the reverse side of the strap, which detect heart rate, it has been customised with temperature and Galvanic Skin Response sensors and a stretch sensor, which measures breathing through the level of chest expansion. The transmitter on the strap sends the heart rate signal to the ‘Bio-OS Data Input’ sensor harvesting unit wirelessly, whilst the other sensors transmit through a cable to the unit.
