Development of a biomechanical energy harvester [PDF]
Journal of NeuroEngineering and Rehabilitation, 2009 Biomechanical energy harvesting-generating electricity from people during daily activities-is a promising alternative to batteries for powering increasingly sophisticated portable devices. We recently developed a wearable knee-mounted energy harvesting device that generated electricity during human walking. In this methods-focused paper, we explain the
