8. Introduction • During space flights, astronauts are exposed to a harsh environment with many factors that pose threats to their health and well being. • Monitoring the state of vital physiological parameters is essential for detecting medical conditions that may result in mission failure. • The design of a portable biomonitor is proposed to help assess astronauts health status in space.

9. Goal • To develop a minimally invasive portable biomonitor suitable for use by astronauts during space flights. Biomonitor for NASA Astronaut wearing a biomonitor

10. Specifications • Monitor vital parameters related to heart, brain and muscle activity, as well as oxygen saturation in hemoglobin and radiation exposure. • Equipped with a sound and visible alarm in case any of these parameters reach a dangerous level. • Size will be miniaturized, designed not to interfere with any physical activities, and will have appropriate mechanical robustness.

11. Specifications (con’t) • It will include a telemetry system for continuous recording of bio-signals within a PC or external storage device. • Resist electromagnetic interference (as might be encountered near other electrical equipment / antennas / environment), as well as produce minimal electromagnetic interference itself. • Under the worst case scenario of failure, the device will pose no electrical or chemical risk to the user

12. System Design • Signal conditioning (amplification + filtering) for: • Electrocardiography • Electromyography • Electroencephalography • Oxygen saturation • Radiation exposure sensors. Acquisition Amplification Signal Processing Transmission Block Diagram of biomonitor system

13. Stand alone device designed with a programmable microcontroller (Texas Instruments) ~$12.00 • Low power consumption • Digitization of biosignals in real time • Digital filters • Custom operation software • Calculation of Heart Rate and trends • Visual and Sound Alarms • Numerical values visualized in a built-in liquid crystal display (LCD).
