In upcoming time there is a serious threat on fossil fuels like diesel, petrol and natural gases, because all these fuels are non renewable forms of energy. These source of energy depleted very rapid rate and after some decades they completely exhausted, so we should have to prepare to face this challenges. Alternative energy will become increasingly important as fossil fuel supplies inevitably run out or environmental damage sparks consumer awareness. The search for a viable energy alternative will continue until these alternatives can address the dynamic demands of the electrical grid and storage limitations. Piezoelectric devices, used for harvesting the vibrational energy of roads and walkways due to traffic, can produce electrical energy that is predictable (based on traffic patterns), and locally storable. There is a piezoelectric material which used for converting mechanical pressure (vibration) into electrical energy. Piezoelectric material works on the principle of the charge output signal proportional to the applied force or pressure.
