| Summary: | Development of an energy harvesting system has become crucial due to the advancement of electronic devices. Vibration based Energy Harvesting has received growing attention over the last decade. Lead Zirconated Titanite (PZT) sheet used as the active material of the energy harvester. However, it has limited power density and it is rather brittle. Thus, the purpose of this work is to enhance the PZT energy harvester bandwidth frequency using thermoplastic polyurethane rubber. The PZT is slotted in between rubber with different thickness and hardness with tip mass of 10g. The PZT was shake at acceleration of 0.25g. It was found that the frequency bandwidth has increased by 35.5 %, percent voltage increase was 12.67 % at natural frequency of 70 to 90 Hz. Last but not least, the voltage and power output were increased by 12.67 % and 28.3 %. |
