However, scientists from the Harvard School of Engineering and Applied Sciences. John A. Paulson developed a new model. It is based on the use of ultrasound to measure the way a person’s muscles work while walking.
A portable ultrasound system was attached to the calf muscles of the subjects during the testing of the equipment. The system could determine the muscle profile after just a few seconds of walking or after one step in a suit. In addition, when comparing the amount of metabolic energy expended by participants with and without a suit, it was found that the development reduces metabolic energy when walking at different speeds and on different surfaces.
It is also noted that the exosuit quickly adapted to the speed and slope of the surface as they changed.
