Exoskeleton leg brace: Better Walking of Disable

Scientists have invented the first purely mechanical device to impart an extra spring in the footstep without the need for electric motors or batteries. Tests have shown the spring-loaded brace worn on the lower half of the leg can improve walking efficiency by about 7 per cent, which is equivalent to removing a 4kg (9lb) load from someone’s backpack.

Inexpensive, lightweight “exoskeleton” device boosts the performance of the calf muscles and the Achilles tendon by absorbing small amounts of energy when the foot hits the ground, releasing it again when the foot is lifted through the air.

Generally people spend more energy while walking and this device uses the mechanical clutch to hold a spring as it is stretched and relaxed by ankle movements when the foot is on the ground, helping to fulfil one function of the calf muscles and Achilles tendon.
