Development and Analysis of Footstep Power Harvester – A Case Study for the Viability of the Device in Surigao City

This study develops a footstep generator and its viability to harvest energy in a two-shopping center in Surigao City. The footstep power harvester module was enclosed in a wood-tile type 3x2ft size where parallel piezoelectric were embedded inside to increase the output current and placed strategically in the main entrance where people generally pass through. In this research, a microcontroller was used to regulate the dc from the piezoelectric to the 3.7-volt battery. The voltage sensor, like the current sensor, was used to Figure out how much voltage was contained in two AA batteries. Data collection of harvested energy was done using two establishments, 12hours from 6 am to 12 pm and 12 to 6 pm. The total average amount of harvested power on one 3x2ft size was equal to 668.5 mW. Tripling the footstep power harvester module would increase the power generated to 2W, enough to charge a mobile phone.
