Here is an unpowered ankle exoskeleton that makes walking easier. It is designed to reduce the metabolic cost of walking by approximately 7 percent. That’s like taking a 10-pound backpack off. Researchers from Carnegie Mellon University and North Carolina State University are behind this creation.
This wearable has a mechanical clutch that engages when the foot is on the ground. It takes over the effort of the calf to make it easier for the wearer to move forward. Such a technology can be used in the future to help folks with mobility issues.
