Alternate Source of Energy in Metro Trains Using Piezoelectric Materials

Energy conservation is a process of conquering circulatory waste energy or heat and converting it into usable power which has been continuously attracting more and more researchers interest because of the limitations of traditional power sources. The foremost aim will be to extract usable power which can run various devices having low power requirement such as mobile devices and wireless sensor networks. In airports and railway transports, there is a wide need of replacing the existing source of energy by alternate source of energy. When the roof of the metro trains are engineered with a piezoelectric technology then the electric current produced by the pressure and vibrations of hanging straps hanged inside the metro trains are captured by sensors and converted into electrical charges. However the voltage developed is very few volts but practically it is possible and can be amplified with the use of other systems.
