| dc.description.abstract | Piezoelectric energy harvesters are gaining a lot of interest as an innovative and potentially useful device for the harvesting of energy from vibrations in the environment. A piezoelectric energy harvester cantilevered beam is a tool that permits the conversion of mechanical energy to electrical energy. The beam's dimension structure needs to be characterized to enhance the output power. This thesis presents various dimensions of piezoelectric energy harvester cantilevered beams to obtain their optimum design by finding their highest frequency with the highest power output. The piezoelectric energy harvester model consists of a piezoelectric layer of PZT-5A, an aluminium alloy beam, and a tip mass made of tungsten. Using Ansys Workbench, Modal analysis, Harmonic Response analysis and Piezo and MEMS were set up and run for various beam dimensions. A comparative study of the piezoelectric cantilever beam’s simulated output characteristics was conducted. Results show that the highest frequency for PEH cantilever beams without tip mass and with tip mass is 324.03 Hz and 272.61 Hz, with the power output of 0.000534372 W and 0.000494094 W respectively. The optimal design parameters for a cantilever piezoelectric device have been determined, which refers to Design A from the piezoelectric energy harvesting (PEH) without a tip mass, and Design F from the PEH system with a 5g tip mass. Both designs achieved the highest percentage in voltage and power output. | |
