Electricity from walking

Hi friends,
This is my first Instructable!!!
"ELECTRICITY FROM WALKING",looks like a weird title!!.But it is true that you can generate electricity by just walking over.
The principle is very simple,when you apply a pressure on piezoelectric crystals electricity is developed over the crystal lattice!.
When you walk a pressure is applied to the ground ,utilising this pressure electricity is generated.
You can read the full details from

Step 1 Materials required

Materials required:

Piezoelectric transducers(the thin speakers from the buzzers) - according to the area of the base

Diodes(1N4148 or any smaller diode) - no. of transducers used(one for each transducer)

Base - cardboard or any hard material

Cardboard - cut into small square pieces with side slightly longer than the diameter of the transducer

Soldering iron ,solder, wire strippers ,knives or utility blades,enameled copper wires.

Red and black coloured wires - desired length

where i can find this Piezoelectric transducers . i want this fast and cheaply.
please tell fast .
i cudent understand (the thin speakers from the buzzers) can you please tell fast

[sachingowda]

interesting,,,better to implement on a large scale..

IT"S is COOOOOOLLLLLLLLLLLLLL!!!!!!!!!!!!!!!!!!!!!!!!!..........................

[senowoke]

very interesting...

it is the output ac or dc??
how to stabilize the out put??

[santhosh_r]

The output is AC and the diodes are used to rectify it to DC.To stablize the output use a capacitor.

[Chainfire]

I'm doing a similar project to this, and i want to know a couple things.
Did you account for the polarity of the elements?
Do you actually need the diodes?
How exactly did you hook this up to your voltmeter?
Any references you could provide would be appreciated!

[santhosh_r]

I did not account for the polarity of the crystal as it produces a AC voltage!
Yes the diodes are necessary to convert AC to DC and to prevent the energy produced by one crystal being used by the other to produce sound.

Cool!  Need some of those on my boots!

[alexsolex]

it could be a soooo good idea... if PZB was not so toxic and if you had not to recycle it the proper way..

Your idea is pretty clever anyway, and on wide range could be usefull for many applications (put some under your shoes and get a source for charging phones or mp3 stuff...)

Very interesting!

It is useful also, or only for fun?

[santhosh_r]

It is useful and not for fun!!
