43834 NASA Johnson Space Center, Houston, Texas, USA.
Article Synopsis
- A multifactor statistical model was developed to predict changes in torso shape and lumbar motion in space suits using fabric strain sensors on participants' bodies.
- Physical interactions within pressurized suits may cause injuries during space missions, especially if the suit fit is poor, highlighting the need for effective measurement of body motion inside the suit.
- The model demonstrated an average prediction error of 2.02 cm, accurately replicating subtle soft tissue changes, which can help enhance space suit design and reduce injury risks for astronauts.
