Abstract

In the world where the effect of conventional energy source such as coal and fossil fuel has become the main concern by the earth population, extensive research has been conducted on various renewable energy alternatives, with some of them showing promising potential for the future. Consequently, there is an increasing demand for exploring new clean energy sources, leading to extensive research in this field. Among the explored energy sources, wind power has received significant attention. Nevertheless, traditional wind turbines require high wind speeds, limiting their deployment to specific locations. To address this limitation, this project proposes a novel approach: designing a windcatcher utilizing a single cantilever beam for a piezo energy harvesting system. The primary objective is to design the windcatcher using single cantilever beam for the piezo energy harvesting system, to design a data collection monitoring system for piezo energy harvesting and to analyse the output voltage of different windcatcher designs as innovative piezoelectric harvesters (PEHs). The windcatchers will be specifically designed to capture energy from the induced airflow generated by moving vehicles on roads, highways, and streets. Subsequently, the prototypes were created and subjected to rigorous testing to test the feasibility of this methods. Then, this design has been tested in the lab. At the end of the project, a functional piezoelectric harvester was be developed. Overall, this project is success, and the research aims to explore new avenues in energy harvesting by utilizing the windcatcher design and developing efficient piezoelectric harvesters capable of capitalizing on induced airflow from ground vehicles are achieved. Despite this project nature as a proof of concept, this research has successfully developed a piezoelectric harvester with the max generated voltage is 3.3V.
