Abstract

Electricity has been more significant and in demand in recent years. Many energy resources have been squandered and depleted. A new approach to produce power has been discovered by relying on humans’ movements. The footsteps vibrations produced by humans are usually gone to waste because there were no uses for that. By reusing this wasted energy, electrical energy may be produced. A piezoelectric transducer is the kind of transducer used to detect vibrations. The electrical energy can be produced by converting the mechanical energy by using the transducer. The electrical energy is converted from the pressure produced by human footsteps that are delivered to the transducer. A series-parallel connection is used to connect the piezoelectric transducer. The transducer is then placed on a wooden tile that will function as a footstep platform to produce pressure to the transducer. This tile may be used in a congested location, on a walking path, or crowded area. The goal of this research project is to focus on producing energy using piezoelectric footstep and act as backup power source. Various methods have been taken in conducting the research by referring to previous articles and research to further deepen the knowledge about this project. The results for this project are achieved when the footstep piezoelectric prototype can successfully charge electronic devices and can be monitored by using Blynk applications and controlled through electronic devices such as mobile phones. Different output power have been successfully produced and measured depending on the different human weight and different time to pressure used during the testing. In conclusion, the results of this prototype piezoelectric power outputs shown the potential of this type of renewable energy source to be implemented in congested public area.
