During extra-vehicular activities (EVAs) or space walks astronauts over use their fingertips under pressure inside the
confined spaces of gloves/space-suite. The repetitive hand motion is a probable cause for discomfort and injuries to the
finger-tips. We describe a new wireless fiber-optic probe that can be integrated inside the astronaut glove for non-invasive
blood perfusion measurements in distal finger tips. In this preliminary study, we present blood perfusion
measurements while performing hand-grip exercises simulating the use of space tools.
