In collaboration with the Italian Air Force (ItAF) and Italian Space Agency (ASI), the Italian company REA will conduct an in-orbit test of the Electrical Muscle Simulation (EMSi) suit – an intra-vehicular suit that can monitor and measure astronaut body movement. The suit is made of a material with antibacterial properties and contains sensors to collect data on muscle activity from the arms, legs, and trunk during daily activities. It also incorporates compression properties to help correct the shifts in body fluid distribution seen in microgravity. This project will test the suit during Ax-3 and could be used during future space missions to improve astronaut health and well-being.
