In this modern world, growth of technology is highly increased and the human population. So, we have planned to connect these two things to harvest electrical power which is the ultimate source of all those technologies. This paper presents a literature review of generating power by using piezoelectric materials which converts human's footsteps into electrical energy. Many smart materials are used to generate power from many sources. In those, piezoelectric materials related papers are reviewed under the development of a device to produce electrical energy by using the pressure produced by the human while walking and jogging. The utilization of pressure obtained from compression of floors offered by human footstep pressure across the piezoelectric materials. The same technology is applicable for the long vibration system existing in the world.
