  • Piezoelectric Shoes: Charge Your Mobile Device by Walking!

    Hello everyone.Upon taking AP Physics 1+2 in highschool, I have found that you can not directly connect the piezoelectric generators in parallel since they create AC current.Although the project will still technically work, this explains the lack of efficiency that everyone (including myself) experienced after making the product. If you are still interested in making the project, I'd recommend trying to use bridge rectifiers for each individual piezoelectric generator, then connecting them in parallel by connecting each all the red wires and all the black wires together in a chain(you might have to also regulate each piezoelectric transducer's output so they have the same voltage and current, but I'm not sure) . It's hard to explain, but if you look up how to wire things in parallel it ...

It's hard to explain, but if you look up how to wire things in parallel it should make more sense. If you do try wiring each piezo to its own bridge rectifier, be sure to let me know how it goes in the comment section below!I am thinking about updating my instructions for a 2.0 version soon!My sincerest apologies to anyone who tried to replicate my project with disappointing results.Reference for AC in parallel fact:https://www.physicsforums.com/threads/two-ac-power...
