A team of five engineering students at Rice University has created an energy generating leg brace that harnesses
electricity from everyday walking, which may help power artificial hearts in
The device generates power with every bend of the knee. The energy
produced by a motor attached to the joint of the brace is funneled into a
The leg brace produces 4
watts of energy as the wearer walks and feeds it to a lithium-ion battery.

added a power conversion and storage system that was not present in the device
at the beginning of this year. So we're getting about the same power output,
but we're also able to convert it to direct current and store that into
something useful," Hutson Chilton, one of the engineering student.
energy produced by the device is not enough for the artificial heart. The team
expects a future version to supply energy wirelessly to medical devices.
