Abstract

The development of piezoelectric energy harvester has quickened up in last few years mainly due to semiconductor improvements. Harvesting ambient vibration energy through piezoelectric element is increasing lately due to the technology growing more to use free energy source. The prototype development of bus stand lamp using piezoelectric energy was developed to show the concept of the harvester system. This product overcomes the problem of lacking lighting system for bus stand at rural place. The piezoelectric disc was place on the floor to gain energy from people walking across this area. The location to place this piezoelectric disc is determined in order to maximize the harvesting output power from people step on it. Power that harvested will be stored in the supercapacitor or battery before delivered to the load. This product used light emitting diode (LED) to light the bus stand as energy efficiency of LED is high compared to the traditional lighting. This bus stand is using LDR sensor to make it only turns on light when at night. In this project, two experiments were conducted to determine the maximum output of this piezoelectric harvesting base that can generate. From the experimental results, it show that the piezoelectric energy harvester base can generate a significant output that can charge the battery.
