Abstract

The technology in portable gadgets has been rapidly evolving. Prolonging service time of these devices has been quite a challenge especially in the battery industry. Most mobile devices are charged from wall sockets before they can used and carried away. Thus, the reliability of these devices is limited by their battery capacity and availability of charging outlets. One way to extend service time is to use energy harvesters Several studies were conducted in energy harvesting from foot strikes. For this study, a low cost design has been employed in generating power from heel strikes. A brushless direct-current (BLDC) permanent-magnet motor used as computer cooling fan was modified to run as generator which was then powered by a relatively small bellow-like air-pump. The mechanism was installed in the heel part of a slipper and was tested in speed-walking, jogging, toe-grounded stomping, and jumping the root-mean-square (RMA)voltage output was then recorded for various load resistance and activity rates. The results of the study showed that the phototype is capable of generating about less than a milliwatt and the maximum output of 3 milliwatt was observed in toe-grounded stomping.
