- With the global energy crisis, many technologies in energy harvesting, such as solar, wind, geothermal, and hydraulic power plants, have been developed. This project envisioned to explore the potential of vibrations as a sustainable alternative source of energy through a simple and easy-to-make harvester. Piezoelectric materials that convert vibrations from human activities into energy were applied. A digital multi-meter was used to continually monitor the voltage output of the system. Three trials were done per monitoring. Actual testing to light emitting diode was also performed. Data showed that an output voltage was successfully generated. An average output voltage of 0.52V had a charging time of 20.56 seconds, 1.03V in 33.16 seconds, 1.52V in 60.52 seconds, 2.02V in 88.30 seconds, and 2.34V in 119.71 seconds. An average discharging time of 41.86 seconds per 1mV drop was also recorded. Results suggested that a fully charged device could have a theoretical continuous illumination of approximately 26 hours. In addition, the fabricated device successfully powered a light emitting diode for possible lighting purposes. The experiment established the viability of converting vibrations from human locomotion using a simple wooden box energy harvester and the potential of vibration as one of the most promising sources of energy for powering devices with low voltage electric requirements.
