Abstract

A wearable energy harvesting device includes a harness to be attached to a human leg, the harness has upper and lower portions, each with inner and outer support members for placement along the human leg. The upper outer support member is connected to the lower outer support member by an outer hinge and the upper inner support member is connected to the lower inner support member by an inner hinge. A pendulum assembly attached to the harness oscillates in response to human body motion. The pendulum assembly includes a pendulum, a flywheel mechanically coupled to the pendulum, pulleys including a first pulley mechanically connected to the flywheel and a second pulley having smaller diameter mechanically connected to a ratchet gear, a belt connecting the pulleys, and an electromagnetic generator coupled to the ratchet gear.
