The electrical power generating carpet is a carpet having piezoelectric-based electrical power generating tiles embedded therein. Each energy generating tile includes upper and lower plates, each having opposed top and bottom surfaces, at least one piezoelectric strip mounted on the top surface of the lower plate, and an engaging member attached to the bottom surface of the upper plate. The upper and lower plates are stacked such that the engaging member contacts the at least one piezoelectric strip. In use, when a person steps on the carpet, the upper plate of the at least one energy generating tile flexes, causing the engaging member thereof to apply pressure to the at least one piezoelectric strip to generate electrical voltage. When the person steps off the tile, the pressure is relieved, generating a current. An energy harvesting circuit including a rectifier and a buck converter are connected to the piezoelectric strips.
