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

Step 2: Soldering the Cells(transducers)

Take the cells and solder a stripped enameled wire followed by a diode.
Connect all the other wires in parallel with other cells.
Connect the wires from the diodes' cathode in parallel.
The red wire goes to the diode and the black to all the black wire from other cells.

Step 3: Arranging the Base

Cut the base to the required size.

Arrange the cells on the base with a small piece of cardboard in between the cells and the base.
The cardboard in between must have a small grove cut ,so that the wires soldered can be easily connected and this prevents the cells from breaking when an excess pressure is applied.

Step 4:

Cut another cardboard or any other hard material to the size same as the base and place it over the cells.Vollah! the project is ready to test!
Draw some graphics and stick it to the top cover to make it attractive.

Step 5: Testing


Connect the black wire to the wire that you have connect in parallel to the cells common wire.

Connect the red wire to the wire that you have connected in parallel from the diode.

Connect both the wire to a digital multimeter set to 20V range.
Walk on the project with the top cover fixed. Do not walk on bare cells as it would break them.
If you have connected everything right ,the multimeter would show some reading like 2V or something like that.
The output voltage and power is directly proportional to the pressure applied or in other words the weight of the person walking on it and the time the person is standing on it.

Step 6: Troubleshooting

There is no reading on the multimeter
   Check the cables
      check that the red goes to the diodes' cathode

USES:

-In crowded areas such as railway stations, sub-ways, bus terminus etc.
-The electricity can be used to charge batteries and used for street lights and night lights.
-Emergency exits.
<p>hi bro it seems good project and i have lots of doubt in this can you please contact me through mail: santhoshpro05@gmail.com</p><p>as soon as possible bro waiting for your reply eagerly</p>
<p>can piezo buzzers can be used? </p>
how much amount of current is generated in amperes? please inform me soon &amp; how <br>
current is the measure problem, it doesn't produce much ,may be in nano amps
<p>This problem occurs because your circuit might be having fairly large resistance . To avoid this do this : attach a very small resistance to each circuit in your project, this will improve the current value fairly enough. It helped me in my project of generating electricity using crank shaft generator. Best of Luck, contact me on flyboyravi@gmail.com if you need some help</p><p>Cheers,</p><p>Ravi Pandey </p>
it is producing a farily high amount of voltage but not current...?

Very nice
Nice project
<p>Electricity in this is produced as we take steps right? So there is no continuous power supply. Wont this affect the electronic device? And is there any way to store this energy so that we can use it later and get continuous voltage?</p>
<p>can anything b used instead of a piezoelectric transducers??</p>
<p>Friends,I used this piezoelectric sensor(transducer) to sense the vibrations produced by a small vibration motor.But i used 1 sensor and getting a very small variable voltage.The output is not constant to amplify.can i use many sensors? if yes should they be connected in series or parallel???How to connect??Can i use rubber sheet to transfer vibrations??plz help..</p>
<p>it's beautiful thank you ;-)</p>
<p>hello,I wonder to know can I make it with series piezoelectrics I mean buy doing this can I get more voltage (like batteries)?and how much is the voltage that you got,I can't understand it from the picture.</p><p>why you didn't use one diode bridge instead of lots of diodes?</p><p><strong><em><br></em></strong></p><p><strong><em><br></em></strong></p>
<p>Why is a diode being used instead of the bridge rectifier circuit?</p>
<p>Why is a diode being used instead of the bridge rectifier circuit?</p>
<p>Why is a diode being used instead of the bridge rectifier circuit?</p>
<p>does it depend on the weight of the perso</p>
where i can find this Piezoelectric transducers . i want this fast and cheaply.<br>please tell fast .<br>i cudent understand (the thin speakers from the buzzers) can you please tell fast
<p>hack into a buzzer u'll find a coin like component that is the piezo</p>
very interesting...<br><br>it is the output ac or dc??<br>how to stabilize the out put??
The output is AC and the diodes are used to rectify it to DC.To stablize the output use a capacitor.
how much amount of current is generated in amperes? please inform me soon &amp; how please sir please m doing this as my final year B.E project n m facing problem in finding the current i have got the voltage but its not showing current so please inform me as soon as possible
<p>try a micro or milli ammeter u might get it i'm also atempting to do this project</p>
<p>Hi, Thank you and great work. Can you tell me, where we can buy in Kakinada, Andhra Pradesh and cost of the sensor?</p><p>Aswin</p>
<p>sensor?? u mean the piezoelectric cell right just take it from a buzzer u will get it</p>
<p>ya m also generate but is very big problem for crystal bcs this cracked it under why .......nd how electrcity generate back high tap it after crate electricity is low range ....so wt m doing help me ...think my be final year project .....guide me yaar9028414428 is my contact no</p>
Is there an email I can reach the author with, I have a few questions?
<p>Hi, Thank you and great work. Can you tell me, where we can buy in Kakinada, Andhra Pradesh and cost of the sensor?</p><p>Aswin</p>
<p>COOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL</p>
where do i find the thin speakers from buzzers? Are they found in calling bells in our houses? please reply as fast as possible. <br>
<p>no</p>
Awesome 1
thanks it is very usefull for me
sir i am interested in your idea can you give me any valuable suggestions
how much power do u get with it. are u having any mathematical data regarding to calculate the power from it. <br>
interesting,,,better to implement on a large scale..
IT&quot;S is COOOOOOLLLLLLLLLLLLLL!!!!!!!!!!!!!!!!!!!!!!!!!..........................<br>
I'm doing a similar project to this, and i want to know a couple things.<br>Did you account for the polarity of the elements?<br>Do you actually need the diodes?<br>How exactly did you hook this up to your voltmeter?<br>Any references you could provide would be appreciated!
I did not account for the polarity of the crystal as it produces a AC voltage!<br>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.<br>for more details read<br>http://www.scribd.com/doc/22975115/Project-Building-Instructions-ELECTRICITY-FROM-WALKING<br><br>http://www.scribd.com/doc/22302487/Electricity-From-Walking<br>
Cool!&nbsp; Need some of those on my boots!<br />
it could be a soooo good idea... if PZB was not so toxic and if you had not to recycle it the proper way..<br /> <br /> 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...)<br />
Very interesting!<br /> <br /> It is useful also, or only for fun?<br />
It is useful and not for fun!!
