Energy Harvesting Applications using Piezoelectric Sensors

With the current scenario of global warming and with the rapid depletion of energy resources, the world is on a brink of an energy crisis. In the wake of this, renewable energy seems to be the only escape from this ever so looming crisis. Fossil fuels are a depleting resource of energy. The world is slowly but surely moving towards renewable forms of energy. In third world countries, large population is another problem along with an already existing energy crisis that requires an urgent solution. Renewable energy although developed to some extent is inefficient and cost ineffective. Developing countries like India are looking for solutions to help reduce to load on nonrenewable energy (fossil fuels). To solve this problem the use of piezoelectricity and piezoelectric power generation may be used for power generation and energy and harvesting. The researchers would like to propose some new applications of Piezoelectricity, which do not yet exist ad may be implemented in the near future to solve the energy crisis in India. These solutions involve use of mechanical energy and convert it into electrical energy. This mechanical energy may be obtained from various sources, man-made as well as natural as explained in detail with calculations in this paper.
