  • The Challenges EVA HR•  Maximize the comfort, ease of use, reliability, and accuracy Monitoring•  Minimize the equipments mass, volume, Requirements power, and time for set-up and use Apollo ShuttleSensors Sensors Space Station Hardware
  • Market  Survey/Lessons  Learned  • Many systems rely on perspiration/moisture• Nearby EMI can totally disrupt biomedical signals• Not all systems have local display, ensure data is actually recording• Have no buttons on the device that can be accidentally toggled• The sensor is only the front end - many other factors contribute to final signal quality• Motion artifact remains one of key problems• Wireless an option - but many technical issues remain• Some devices need attention to keeping them in place on the body• Three considerations for sensor contact to skin• Placement of sensors sometimes key• Pick a financially viable company• Get agreement on the definition of easy to don/doff
  • Future Space Medicine Health Care•  Portability and application of nano-technology•  Minimally/non-invasive, efficient diagnostic systems capable of detecting abnormal human function across all body systems•  Health care approaches capable of therapeutic intervention for a wide range of pathological and trauma scenarios
