Energy Harvesting from Vibration of Structures-A Brief Review

Abstract

The shortage and high cost of energy in developing countries of the world has led to the search for other sources of electricity which are renewable and do not constitute to environmental hazards or pollution like fossil fuel. Also, the short life span of batteries which are used to power up important smart devices like the fire alarm makes searching for alternative sources all the more important. This has led to the recent interest in sustainable and renewable energy sources from water, sun, vibration, biological wastes etc. Harnessing energy from vibration amongst other renewable energy sources reduces fatigues in machineries, structures and control systems and effectively dissipates negative vibration energy from buildings, bridges, roads and various mechanical systems. This research paper provides a brief review on the current state of knowledge on the subject of harvesting energy from vibration. The review shows that harnessing renewable energy form vibration is feasible and has a great future.
