														  The End  Users for the proposed Bioastronautics devices are space agencies worldwide  that are involved in human spaceflight activities. The development of a  biomedical sensor net for intravehicular and extravehicular astronaut health  monitoring is sought.  In designing these  devices, we would conform to the most rigorous space requirements as follows:
														  
														    - Minimally-invasive
 
														    - Low mass  and volume
 
														    - Low power
 
														    - High  accuracy
 
														    - Rugged  and reliable
 
														    - Adaptive  and intelligent
 
														    - Easy to  calibrate
 
														    - Multifunctional
 
												    
														  For  biosensors to be minimally invasive, they should be capable of making rapid  readings by drawing nanolitres of fluid samples without piercing the skin. An  additional desirable feature is the ability to detect and measure trace blood  analytes in minute concentrations. Among the possible ”dual uses” could be the  use of these sensors for also monitoring trace contaminants in spacecraft  environments.
