In week 2, we figured out after some research that no matter how strong the magnet is it won't be able to generate enough energy to charge a mobile phone by electromagnetic induction. This is because our design aimed to place a magnet in one shoe and a solenoid in another, but the distance between them was too large.
After learning this we decided to use some other strategy rather than giving up on this idea. Hence, we came up with using gears instead. This is more likely to be successful comparatively. Now we are working on the gear systems to be used. As of now we came up with the gear design below:
"Force is directly proportional to the inverse of the distance squared." [1]

It can be seen in the photo above that a wedge will be pressed in with a footstep; this would drive a vertical primary gear; the motion would drive rest of the gear train and the generator. The generator is connected to Li-ion batteries.
