Enhancement of Power Generation From Electromagnetic Scavenging Tile

Footstep electricity generation tile is designed with an improvement to power the sensors which consumes a small amount of electricity. In a country like China and India, it is very much essential to generate the electricity through these which are going in vain. Production of electricity by burning fuels may serve to some extent by polluting environment. So, even a small contribution of electricity should be considered to electricity as much as possible. Maximum output of 15 Watts is obtained by using both upward and downward motion of a tile. In this permanent magnet synchronous generator is used for its better output and its aptness. Flywheel is used to store required potential energy which was obtained from a human foot applied force and to get maximum inertia as much as possible. Two Oneway clutches are used to make the generation smoothly with less damping in bidirectional movements. Energy output in terms of joules, it obtained a peak more than 2 Joules per step. Fast walking force is taken as input for this paper. Different flywheel with different inertia were used to generate different outputs.
