Design, Development and Analysis of Energy-Harvesting System.

Purpose: Energy-harvesting technology is based on the idea that devices can harvest the energy present in their ambient environment in real time and use it immediately, with or without the need for storage. This investigation focuses on the design, development, and analysis of an energy-harvesting system using commonly available piezo transducers. Methods: The prototype developed converts the energy from the mechanical vibration, due to footsteps, into electrical energy using piezoelectric sensors. Both simulations and experiments are carried out to validate the design and analyze the single and array piezoelectric energy harvester. The simulation results for single piezoelectric sensor have been obtained using LTspice tool. Results: On experimentation, it was observed that, the parallel combination of the array of piezoelectric sensors gives better energy-harvesting capability. Conclusion: The developed prototype demonstrates a low-cost energy-harvesting system that can be used in low-power applications. [ABSTRACT FROM AUTHOR]
