Executive Summary :

Energy harvesting from ambient vibrations has been in the spotlight recently. Indeed, by employing the inverse magnetostriction or Villari effect, it is possible to scavenge the vibration energy by means of induced magnetization change in the material to generate electric power. This opens the possibility to have a regenerative source of electrical power, especially useful in harsh environments. Vibration based power generation technology can be utilized effectively in various fields of applications: The world is looking forward for vehicles which are more and more efficient. The vibrations, due to the internal combustion engine operations and vehicle movement and interaction with the road irregularities may be sources of power generation. The harvested power can be used to recharge the vehicle battery or for feeding the monitoring sensor nodes. Energy harvesting technique from vibration has a promising future in civil engineering. The magnetostrictive wireless sensor network (WSN) can be implemented for the health monitoring purposes of tunnels & bridges and to prevent accidents caused by the vibrations of cars. Another potential field of application of magnetostrictive energy harvesting is the biomedical one. In this case, the source of vibrations is the human gait (walking or running) and it could be used to power devices aimed to monitor human health conditions. It is possible to extract electrical energy from the mechanical vibrations of wave energy, machine vibration etc. We propose some tentative energy harvesting device designs based on Iron-Gallium alloy, Terfenol-D, Metglas which is capable of generating electrical energy efficiently from ambient vibrations. Focusing on this project, various experiments, simulations, analysis will be done under this work. Some novel structures of energy harvesters will also be implemented & their characteristics will be verified experimentally. Energy conversion efficiency will also be measured. This effort is more judicious in the context of present scenario where more and more importance is being imposed on the non-conventional energy generations especially the developing country like India.
