The new design means users have more control than with a typical prosthetic.
A new type of prosthetic limb has been designed with materials originally designed for the International Space Station.

The new design has free-swinging knee and regenerative braking features meaning users have more control than with a typical prosthetic.

The limb is also more energy efficient, capturing and storing energy as the foot hits the ground.

A new robotic prosthetic leg prototype offers a more natural gait while also being quieter and more energy efficient than other designs, researchers report.

The key is the use of new small and powerful motors, originally designed for a robotic arm on the International Space Station.

The streamlined design offers a free-swinging knee and regenerative braking, which charges the battery with energy captured when the foot hits the ground. This feature enables the leg to more than double a typical prosthetic user's walking needs with one charge per day.

"Our prosthetic leg consumes approximately half the battery power of state-of-art robotic legs, yet can produce more force," says Robert Gregg, an associate professor of electrical and computer engineering at the University of Michigan and a member of the university's Robotics Institute, who led the study while…
