The Muscle Stimulation Patch is designed to represent the aims of the experiment, namely apply inflight a small electrical muscle stimulation (represented by the yellow triangle) to the leg muscles (white arrows) of astronauts on-board the ISS, to sustain their muscle mass and performance, and measure with several experimental techniques (represented by the white cuvettes) in which way the muscles respond to this exercise modality delivered in Space (represented by the green stars).
The patch’s colors represent the Countries of the team members (Italy, United Kingdom, Germany, The Netherlands and Switzerland).
