Researchers have created an exoskeleton boot that reduces the wearer's energy use by 7 percent without batteries or motors.
The boot is remarkable not only for its motor-free operation, but also because some experts had doubted that human locomotion could be improved upon at all. Created by a team from North Carolina State University, the exoskeleton features a spring that reaches from the back of the foot to the back of the knee and works as a sort of Achilles tendon-assist, storing energy from the down-step to use to push up next time.
