Abstract

In this era of globalization, energy is essential to life and all living organisms. Our energy choices and decision impact Earth’s natural systems in ways that people may not be aware of, so it is essential to choose the energy source carefully. Energy is used for agriculture, transportation, information technology and human communication. Renewable energy should be used instead of non renewable energy to reduce greenhouse gas emission. Piezoelectric is a common sources of energy harvesting. Energy harvesting is a process of extracting, converting and storing energy from the environment that can generate from pressure, vibrations and motion. Piezoelectric can generate energy when pressure applied to it, the materials will convert mechanical energy to electrical energy and conversely. The aim for this project is to produce a renewable energy source for personal use during emergency situation, to develop a piezoelectric power generation system on shoe that can generate electricity and to develop a piezoelectric power generation on shoes that can generate electricity. This shoe power generation using piezoelectric project used a pressed piezoelectric sensor element as an input to generate electricity and to store it in a battery for charging purpose during an emergency case. The bridge rectifier is used to convert the AC voltage to DC voltage. As the result, the piezoelectric energy harvester system prototype needs to harvest the energy and convert it to electrical energy to charge the battery and the output. The data collected from the project prototype system are then analyzed, evaluated and maintained for the further improvement.
