Development of Piezoelectric Tiles That Utilizes Human Kinetic Energy From Walking to Provide 48 Watt-hours of Energy for a 16W Led Light Bulb

Abstract

As the population increases per year, the power demand also increases that is why scientist and engineers venture to renewable energy to acts as substitute for non – renewable resources such as fossil fuels. This study focuses on renewable energy specifically piezoelectricity or the conversion of mechanical stress to electrical energy which can be utilized to produce energy for light bulbs and other electrical equipment. The researchers were able to fabricate and test three energy harvesting tile that consist of 72 pieces of piezoelectric transducer per tile and the materials used are from local hardware and furniture shops. The tiles are subjected to three tests (Maximum and minimum load test, AC/DC Voltage test and Energy harvesting test) to determine the electrical capacity of each tile. The results showed that the tile can withstand the weight allotted by the researchers and each tile have produced electricity every time someone steps on the tile.
