The exoskeleton displacement reduces the metabolic cost of walking.

Store energy and save energy.

Many devices have been developed to harvest energy from walking or running. But using these devices often comes at a cost for the wearer in the form of increased metabolic needs. And faculty Design a device that can harvest mechanical energy from natural walking and convert it into usable electrical energy while reducing the user’s metabolic energy use (see View by Riemer. And faculty). The key to achieving “Something from nothing” comes from designing a device to use the exoskeleton resistance control of the muscle-centered knee joint. To reduce the strength of the muscles working at the end of the leg swing cycle.

Evolutionary pressures have caused humans to walk in a highly efficient manner that saves energy. This makes it difficult for the exoskeleton to reduce the metabolic cost of walking. Despite the challenges But some exoskeletons can help reduce the metabolic costs of walking. Either by adding or storing and returning energy. We show that the strategic use of exoskeleton that removes kinetic energy during the oscillation period of the gait cycle. Reduces walking metabolic costs by 2.5 ± 0.8% for healthy male users. while converting the removed power to 0.25 ± 0.02 watts of electrical power by comparing the two load profiles. We show that the time and size of energy removal are critical to the successful reduction of metabolic costs
