Application of Piezoelectricity in DMRC

What have we done to our environment? Everyone should ask this question to themselves. Due to increasing demand of energy, the world is leading towards the depletion of carbon fuel. Today the need of the hour is the correct transformation of energy and reuse of energy. Fossil fuel based power generating technologies have much large amount of carbon emission leading to climate change. Today the need of century is to move towards carbon free energy and find every possible way to do so. One of the possible implementation is what we have done in our research. We at Maharaja Agrasen College, University Of Delhi, have tried to use Piezoelectricity, which is a charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress, pressure and vibrations. We came up with an idea to convert pressure and mechanical stress into electricity in Metro stations. The energy people apply in walking on metro station platforms is converted into electric charge which is converted into electric voltage required to charge the battery using the piezoelectric transducer generators.
