IDEA

Have u ever opened a dc motor??

If u hve u san see one type of magnet which is very soft like rubber. I think this will be useful.

Let’s discuss the design for the piezeo mechanism here, please list your thoughts and ideas. :)

Great post. See below.

“I would like to see data on generation of power using piezo materials, conversion efficiency, and energy storage. Then add your constraints, such as the size of a shoe. What is your target, enough power to do what?! Notice how I don’t use voltage or current. It is because power is the end game. You showed a video of voltage generated when compressing piezo materials. What was the current? How much of that energy made it to the battery as stored energy? Definitely do your research, especially if the majority of your proposed work has already been done. How much energy do you think you could get from spinning a micromotor using a compressed chamber of focused air?”

A similar project was proposed by DARPA some while back, they had intended to use this method in the shoes of soldiers to recharge their flash lights etc. But it was later dropped due to constraints on the amount of power produced. In theory it looks like a good project, however in reality it is not practically feasible i guess. I cant say much about the current advancement in piezoelectricity in general so perhaps it may be possible now. However do check DARPA’s project on this very subject and their findings before commiting yourself

there are few spots in our feet which create more pressure than other spots. if the shue is not providing enaugh power we can add some extra power sources to our knee… which will create electricity by the movement of knee and other joints of leg
