Abstract
The generation of electricity by renewable energies is an important need of today's society. Piezoelectric energy harvesting is one of these useful technologies which can generate electricity by applying external force on piezoelectric material. This study illustrates more power generation from piezoelectric tile by changing the situation of piezo discs and connect to proportional electrical circuit. Two different designs of piezoelectric tile are presented by performing experimental analyses. The experimental results showed that placing piezoelectric elements in a bending position leads to higher power generation in comparison with traditional flat positioning, which was approximately 78 times far superior. It is also revealed that by design of an electrical circuit, the tile can be advantageous for lighting in crowded sidewalks with required lighting time. The results of this paper can be beneficial in the design and fabrication of these tiles for different applications.

Renewable green energy production recently is noteworthy due to the negative environmental effect of global warming caused by the consumption of fossil fuels
Piezoelectric materials have special characteristics that could be able to use as a power source in a piezoelectric energy harvesting system
Piezoelectric materials are known as anisotropic dielectrics that some of them have ferroelectric or nonferroelectric properties
Summary
Renewable green energy production recently is noteworthy due to the negative environmental effect of global warming caused by the consumption of fossil fuels. The application of piezoelectric in piezoelectric energy harvesting has been increasing It will make an enormous market in the foreseeable future. This approach of energy harvesting exists in many concepts such as sidewalk power generation [10,11] or other hectic areas like highways or speed breakers [12] to generate the power from converting kinetic ene11rgy to electricity and harvest the generated power to rechargeable battery and capacitor. This paper is called the design and construction of piezoelectric energy harvesting tile, which measures the energy of the tile by changing some of its mechanical parameters and electronic circuits, and compares the effect of changing the parameters on the final power generated in an experimentally manner
