Abstract

Ambient vibration is one of the main sources of energy harvesting and for the past few years it has attracted many interests in design and development of vibration based micro generators. Energy harvesting is also known as energy scavenging is the process of extracting residual ambient sources into usable electric energy which can be used to power-up small electrical devices that require very low power consumption such as wireless sensor nodes and wearable devices. The aim of this project is to investigate useful ambient vibration sources that have a great potential for energy harvesting. The research work comprises process of identifying, measuring and analyzing the identified ambient vibrations which is in the scope of low level of acceleration; <1g. Then, the obtained vibration raw data will be transformed from the time domain into frequency domain by using appropriate mathematical tool. At the end of the project, a summary of various vibration sources is presented in terms of vibration frequency and acceleration level. Suggestions of micro generators developed by other researchers that suit to the identified useful ambient vibration sources for energy harvesting applications is also presented.
