Collection Item Summary:

This biobelt and bioinstrumentation assembly is likely a non-flight medical monitoring system from the Skylab program. The biobelt and harness assembly included an electrocardiogram to record heartbeat, a cardiotachometer for heart rate, an impedance pneumograph for respiration rate, and two sets of electrodes. 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 supported the Skylab goal of understanding the body's response to long-duration spaceflight.

NASA transferred this assembly to the National Air and Space Museum in 1976.
