Abstract

Piezoelectric can generates and stores electrical energy for later use using non-renewable resources like the sun's heat and the wind's vibration. A new energy source require to meet the rising demand due to the depletion of fossil fuels and non-renewable energy. In this work, piezoelectric energy harvesting was studied. In this experiment, piezoelectric energy was measured using multimeter. In this project, indicator used for the output of piezoelectric 8x8 matrix led. Vibration is detected by the piezoelectric sensor, which then transforms mechanical stress into electricity. Piezoelectric sensors are linked in series-parallel connection. The pressure-point footstep tile is then modelled after it using board. A 18650 lithium-ion battery stores the small amount of voltage produced by pressure on a piezoelectric sensor. Piezoelectric AC is converted using bridge rectifiers. This initiative will be applied to stairwells, sidewalks, and other busy areas. DC loads, such as a mobile, can be powered using piezoelectric tiles. Piezo sensors undergo mechanical stress, which causes energy to be stored in the battery. The major focus of the study is on ways to improve power generation through circuit design optimisation and output enhancement and amplification adaptation. An analysis of the differences between the output voltage from the different diameter and quantity is carried out.
