Collection Item Summary:
The auxillary biosensors were part of the Apollo bioharness assembly worn under either the intra-vehicular (IV) or extra-vehicular (EV) pressure suit. This sensor unit was flown on Apollo 11 in July 1969, though not worn during the mission. 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 bioharness components consisted of an electrocardiograph signal conditioner, an impedance pneumograph signal conditioner, and an DC-DC converter, along with sensors placed on the body of the astronaut prior to flight. These instruments monitored the physiological functions of the astronaut.
Transferred to the National Air and Space Museum from NASA in 1970.
