A human gait energy harvester shoes was designed to passively harvest part of the kinetic energy available during walking. In this work, two designs were considered. The first one is using mechanical system and the second is using piezoelectric. In the first design, a swing arm is used to drive an one-way bearing and transmit the torque to the 1:58 ratio gearbox in one direction. This step-up <br /> <br /> <br /> gearbox then finally drive a pair of generators. This mechanical system was designed to fit in the sole of a standard running shoe, which the swing arm compressing once during each heel strike. The second design is putting <br /> <br /> <br /> piezoelectric inside the shoe sole and will bend because of heel strike. An interface circuit is needed to make the piezoelectric output voltage properly measured. Both of the designs then are tested by a ‘tester machine’. The machine will simulate human walking process with speed of 1,2 steps/second using a specifically designed cam. The voltage data can be measured and stored in digital data using LabTech software. The average output power from this test is 0,1 mW.
