Harvard researchers have developed an exoskeleton that automatically adjusts based on how the wearer is walking. A portable ultrasound system takes measurements of the calf muscles to estimate the amount of force produced by those muscles. Using these measurements, researchers develop a personalized assistance profile. The exosuit then automatically prescribes the. amount of assistance needed for different walking speeds and slopes.
The exosuit can automatically determine the assistance a person needs for different walking speeds and slopes. SEAS researchers plan to move forward by testing how the system does with constant real-time adjustments. When researchers measured the metabolic energy used with and without the suit, they found that the suit significantly reduced the amount of energy used.
