This paper presents a human motion based electromagnetic energy harvester for bio-medical devices. This harvester is composed of a Teflon tube, cylindrical magnets, rubber spring and wound coils. The developed energy harvester is tested on an experimental setup which has been developed to test power generation capability of the device with the vibration shaker at 3 g acceleration level. The combined open circuit maximum voltage of 4140 mV is generated by the harvester at 19 Hz and 3 g. Moreover, the harvester produced an optimum load power of 1.89 mW at a load resistance of 25 W and successfully recharges a 1.5 V battery in 60 min.
