The sensors for this biobelt assembly consisted of an electrocardiograph signal conditioner, an impedance pneumograph signal condtioner and a DC-DC converter. They fitted into the biobelt which was constructed of a cotton duck base with Teflon-coated Beta-cloth pockets. The biobelt was fitted with snap fasteners which attached to either the constant wear or liquid cooling garment, and was worn close to the skin underneath the inflight coverall garment or spacesuit.
