Abstract

Energy harvesting is the process by which energy is derived from the external sources from hydropower, solar energy and many more. This project involves in the design and characterization of vibration based electromagnetic energy harvester system. This type has high potential to be investigated and utilized. The main purpose of this project is to improve the previous design and suitable to be used for low power applications such as the wireless sensor network. In developing the new prototype, both electrical and mechanical improvement of the previous design are considered. Utilizing the fundamental Faraday’s law, it serves as a succinct summary of the ways a voltage (or emf) may be generated by a changing magnetic environment. The expectation of the new prototype is the improvement of the overall efficiency in both the output power and also bandwidth. The prototype is design using the engineering software tools such as AutoCAD. Finally, the completed design will be followed by device fabrication. To investigate the performance of the prototype, both the electrical and mechanical characterization have been performed such as the open and close loop voltage, impedance matching, resonant frequency and bandwidth. From the characterization process, it was found that the open-loop and close-loop voltage produces by the device is 5.729 V and 2.920 V, device internal resistance is 560  , device resonant frequency occurred at 29.4 Hz and device bandwidth 9 Hz which are better than the previous prototype.
