During the Phase II Lunar Health Monitor program, Orbital Research will develop a second generation wearable sensor suite for astronaut physiologic monitoring. The low profile system will be appropriate for both Extravehicular activities (EVA) and Intravehicular activities (IVA) monitoring scenarios. The EVA and IVA wearable platforms are capable of monitoring a complete physiologic profile of overall astronaut health status. Sensors of respiration, body temperature, acceleration and cardiac data are included. Inclusive in this sensor suite is Orbital's FDA cleared and patented dry recording electrodes. The sensors are held to the body via the garment and function without any tapes, adhesives or gels. The sensors are mechanically connected to the sensor suite. The mechanical connections allow sensors to be semi-permanently interfaced with either the EVA or IVA designs. These connectors allow sensors to be added, removed or replaced based on monitor application or anatomical constraints. The Lunar Health Monitor is designed to be continuously worn serving as a safety mechanism for out of vehicle exploration missions and a monitoring device for applications such as in orbit fitness assessment. The Lunar Health Monitor is easy to don and doff and non-encumbering to routine and functional tasks.
