PIEZOELECTRIC ENERGY HARVESTING MODEL FROM VIBRATION: EFFECT OF PATCH MATERIALS AND DIFFERENT SOURCE OF VIBRATIONS

Abstract

Piezoelectric devices are the device that used to convert mechanical vibration to electric energy. Numerous of study have propose related to piezoelectric energy harvesting over the past years for the implementation in this country. Malaysia has huge numerous potential for piezoelectric energy harvesting and it will be one of the reason towards green technology. However, the usage of piezoelectric as energy harvester has yet facing with the reliability and durability issues, and in addition, its working mechanism is not yet fully understood to become more essential to achieve an environment friendly harvester as well as sustainability energy generator. This research is conducted by gaining the data and the amount of energy that was harvested from vibration at certain place with different materials. On the other hand, this paper focus on the development of piezoelectric model vibration harvester using MatLab Simulink. The model development based on the transfer function for the piezoelectric sensor for Barium Titanate, Lead Zirconate Titanate and Zinc Oxide patch actuator. From the results, the highest direct current generated will be the railway vibration response. Based on the current generated data, the comparison has been made in comparison of the energy harvested using T8 Equivalent LED Tube.
