Utilization of Pedestrian Movement on the Sidewalk as a Source of Electric Power for Lighting Using Piezoelectric Censors

In big cities, walking activity is very high, especially in the center of community activities such as trade centers, offices, and education. Therefore a good pedestrian facility is needed regarding safety, comfort, and beauty. But now the pedestrian facility mostly becomes a five-times trading area or even a place to plant shade trees and also made as a parking location. The purpose of this research is to design the sidewalk design with the latest innovation, to attract the public to use the sidewalk to walk, by making the street as an independent power source by applying Piezoelectric Sensor Technology as energy conversion media, calculating the average power in every single step pedestrian, and the average number of walkers. The results of this study can be seen that with the design of the sidewalk in such a way as to get, for every 1 step footing produces a voltage of 6.8 V and power 0.000319 Watt when given 441 N style, the voltage will continue to increase as the force gets heavier in giving to piezoelectric, in this design the author uses 4 pieces of piezoelectric arranged parallel in one-pieces media, with an average of 3207 steps per minute needed to be a source of energy.
