Collection Item Summary:

This bio-harness was flown aboard Apollo 11 in July 1969, but was not worn during the mission. It is not identified as to which astronaut it was assigned. The Apollo Bio-Harness Assembly was worn under either the intra-vehicular or extra-vehicular pressure suit.

The complete assembly consisted of a cotton duck belt fitted with snap fastners and teflon-coated beta cloth pockets, which attached the assembly to either the constant wear garment or the liquid cooling garment. The components consisted of an electrocardiograph signal conditioner, an impedance pneumograph signal conditioner, and a DC-DC converter. These instruments monitored the physiological functions of the astronaut.

NASA transferred these sensors to the Museum in 1970.
