They don’t store the energy, but kids shoes have a mechanism that generates enough electricity to make LEDs flash when they walk or jump.
They can store energy using piezoelectric materials in the right manner(though we only get to store very small amounts of energy)
Yes and this is by far the most concerned area of this project - to increase the storage capacity of the sole. If we are able to somehow achieve a good no. I think it will be a very good medium of energy generation.
Hi Mr. Smith , as we will require guidance and resources in this regard I would like to invite you to our team .
