Generate Electricity by Walking

Hello every one do you think that we can generate electricity by walking???

yes we can

by using piezoelectric disc

how it's work ??

the piezoelectric disc will produce current when pressure is applied to it

now we are going to see how to make use of it

1. piezoelectric disc
2. two wires
3. LED
4. shoe

now solder the two wires with piezoelectric disc then connect those wires to the LED

then place the piezoelectric disc on the shoe now you can able to light up the LED while walking
