According to an article posted on Plos One, researchers Steven H. Collins (Department of Biomechanical Engineering, Delft University of Technology, Delft, The Netherlands) and Arthur D. Kuo (Departments of Mechanical and Biomedical Engineering, University of Michigan, Ann Arbor, Michigan, United States of America) have developed a new prosthetic ankle that recycles energy through the natural gait of walking. They have mimicked the natural push-off of a human ankle and using a microprocessor to control the device, capture the energy normally dissipated by the leg. This new technology requires less than one watt. Perhaps this same technology can be used by developers of Human Exoskeletons.
