Hi, this is Swatam and now I am going to teach you How to generate electricity by walking
Step 1: What Are Piezoelectric Materials
Piezoelectric materials are materials that produce an electric current when they are placed under mechanical stress. The piezoelectric process is also reversible, so if you apply an electric current to these materials, they will actually change shape slightly.
There are several materials that we have known for some time that posses piezoelectric properties, including bone, proteins, crystals (e.g. Quartz) and ceramics (e.g. Lead Zirconate Titanate).
However, in May 2012, it was announced that University of California Berkeley lab scientists have found a mechanism of harnessing piezoelectricity from viruses. This is the first time a biological material has been used to make piezoelectricity.
Step 2: Start Collecting Materials
You will get piezoelectric materials in buzzers like the one above in the pic
You can buy it on Amazon. (http://www.amazon.in/20mm-Piezo-Transducer-Buzzer-5-Pack/dp/B010SE0JSA/ref=sr_1_1?ie=UTF8&qid=1478427596&sr=8-1&keywords=piezoelectric
- Piezoelectric materials (about8 to 10)
- Soldering machine
Step 3: Soldering the Piezoelectric Materials
Important Note- all the piezoelectric materials should and must be connected to each other given in the picture so that the total electricity is given to the load.
Step 4: Testing
Now you can amaze everyone with your scientific brain
