“…In this research, two-phased triangular bimorph piezoelectric energy harvesting devices based on the mechanical force of human footsteps are used to create and simulate smart flooring tiles. [1] This article aims to create a functioning model of a piezoelectric tile, which is able to store energy in response to pressure. Voltage is produced by the tile and is then further stored in a capacitor.…”

The urgent need to lessen the effects of climate change and lessen our dependency on fossil fuels is driving an ever-growing demand for sustainable and renewable energy sources. The idea of power harvesting tiles has come to light as a creative and viable approach to this worldwide issue. When incorporated into roads, walkways, and pavements, these tiles have the ability to capture the energy generated by foot traffic and transform it into electrical power.An overview of the idea and technology underlying electricity harvesting tiles is given in this abstract. Usually, these tiles have kinetic or piezoelectric energy harvesting systems installed, which use the mechanical stress caused by footfall to create power. People's footsteps cause vibrations on these tiles, and those vibrations are converted into electrical energy.

“…The geometry of the piezoelectric cantilever beam incredibly influences its vibration collecting capacity as well. Truncated shape such as triangular [4], [14], [15] and trapezoidal with rectangular cross segments proven to be better energy harvester as compared to the traditional design due to a more uniform strain distribution along the beam. To use this type of energy harvester, the resonance of the surrounding needs first to be assessed as the properties of the whole structure is fixed, thus resulting to a fixed natural frequency and frequency bandwidth.…”

Energy harvesting devices are needed as an alternative to batteries as it is costly to power up wireless sensor network. However, the power generated and operating bandwidth for the typical energy harvester are still compromised. Therefore, in this work, the use of permanent magnet in Piezoelectric Energy Harvester (PEH) is proposed to increase the operating bandwidth. A simulation study was conducted using COMSOL Multiphysics software to observe the effect of mechanical tuning using magnet on the voltage produced. It shows that PEH with oscillating magnetic field is capable of reaching generated peak power of 0.775 mW and increase the operating bandwidth by 10%. Experimental setup was also fabricated to further validate the observation at different polarities and varying distances with permanent magnets. It is observed that while the peak power achieved in the attractive mode is smaller as compared to its counterpart, however, its bandwidth is larger.
