Abstract

The energy crisis is worsening as non-renewable energy resources are depleting and contributing to climate change. The solution lies in renewable energy sources, one of which is piezoelectricity. Piezoelectric elements show promising results in generating small amounts of electricity when compressed in everyday applications. The goal of this project was to use these elements to harvest energy from the repetitive motion of a rocking chair, which supplies constant compression. Twenty piezoelectric discs, each connected to a bridge rectifier to convert AC power to DC, were mounted onto a modified chair. The elements were then wired in parallel to charge a lithium-ion battery. With adjustments, the piezoelectric chair could provide a clean solution to charging small electronic devices in public and private spaces while avoiding the drawbacks of non-renewable energy resources.
