Biomechanical Regenerative Braking Energy Harvester: A Systematic Analysis

Regenerative braking is a well-known technology applied in electric vehicles to achieve high energy efficiency through an energy-recovery mechanism. The same concept has been robotic applications, such as legged robots, lower-limb prostheses, and biomechanical harvesters. In particular, harvester enables humans generate watts of power while simultaneously assisting the human joints during walking. this study, systematic analysis regenerative was conducted. First, we reviewed design considerations each component designed energy-harvester prototype with density process. Subsequently, dynamics its effect on biomechanics were analyzed device testing testing. demonstrated 3.3 W/kg for level-ground walking We evaluated muscle activities joint kinematics versatile scenarios sloped downhill walking, hamstring activity assisted by torque generating 1.2 W 0.7 W, respectively, negative work phase. Meanwhile, confirmed that generated rather positive phase interfering quadriceps activity. Comparing previous knee-joint-driven harvesters, our shows relatively level even slower speed without any special
