Dissertation note: Project paper (Bachelor Of Mechatronic Engineering)-- Universiti Malaysia Pahang – 2013 Abstract: The objective of this study is to validate the experimental modal parameter of electromagnetic energy harvester using Finite Element Method (FEM). The performance of the vibration- electromagnetic energy harvester is investigated for different number of coils and length of beam. The relationship between the excitation frequencies and the mode shapes of the energy harvester produced has been analyzed. An electromagnetic energy harvester device was designed and implemented with modal testing is required to gain dynamic characteristic. The parameter used by varying three set of coils including 350 turns, 700 turns and 1050 turns and varying three different length of beam including 9 mm, 11 mm, and 13 mm. An analysis setup consists of FEM simulation with modal analysis and magnetostatic arrangement. The result showed that energy harvester design analysis using FEM indicates magnetic flux path, magnetic density and intensity. The magnetic flux from FEM validated with theoretical calculation and regardless of the parameter, the same set of natural frequencies will be obtained. These shows that the power can be generated and can be improve by varying the number of turn of the coil and length of beam. The increase number of turn coils and length of beam will increase the value of magnetic field intensity.

The objective of this study is to validate the experimental modal parameter of electromagnetic energy harvester using Finite Element Method (FEM). The performance of the vibration- electromagnetic energy harvester is investigated for different number of coils and length of beam. The relationship between the excitation frequencies and the mode shapes of the energy harvester produced has been analyzed. An electromagnetic energy harvester device was designed and implemented with modal testing is required to gain dynamic characteristic. The parameter used by varying three set of coils including 350 turns, 700 turns and 1050 turns and varying three different length of beam including 9 mm, 11 mm, and 13 mm. An analysis setup consists of FEM simulation with modal analysis and magnetostatic arrangement. The result showed that energy harvester design analysis using FEM indicates magnetic flux path, magnetic density and intensity. The magnetic flux from FEM validated with theoretical calculation and regardless of the parameter, the same set of natural frequencies will be obtained.
