Collection Item Summary:

An astronaut on the Skylab 4 mission wore this set of small biomedical devices to monitor their condition during launch, extravehicular activity, return, and for occasional checkups. The biobelt and harness assembly included an electrocardiograph to record heartbeat, a cardiotachometer for heart rate, an impedance pneumograph for respiration rate, and two sets of electrodes (missing from this set). The electrodes attached to the crewmember's chest and plugged into the instruments on the biobelt, which was snapped onto an undergarment. The cable bundle from the biobelt connected to a communications cable for data transmission to medical staff on the ground. The biobelt enabled basic biomedical monitoring during critical phases of the mission and also supported the Skylab goal of understanding the body's response to long-duration spaceflight. This particular biobelt was returned from the final Skylab mission.

NASA transferred this to the Museum in 1976.
