| Abstract | This paper details the modeling, simulation and experimental analysis of piezoelectric energy harvester designed for low power devices like wireless sensor network nodes. The ultimate goal of this work is to harvest the energy available in the vibration environments viz. industrial machineries, ducts, automobiles systems, road infrastructures, railway tracks etc. Efficient extraction of energy from the vibration source is essential and can be achieved by adopting the principles of maximum power transfer and impedance matching. Impedance matching reduces losses in the harvested energy between the systems being coupled, mechanical to electrical to rectifier to DC-DC converter to the load. The selection of suitable DC-DC converter topology and components for converter enables optimal harvesting of energy from the piezo transducer. The piezoelectric energy harvester system components viz. piezo element, rectifier, dc-dc converter, load were modeled and simulated using SPICE. This modeling enabled to find the optimal energy profile (number of piezo devices and source of vibration energy) of the harvester and optimal duty cycle for the wireless sensor node based on the available energy. The modeling and simulation results have been compared and analyzed with the experimental results. It has been validated from the results that, it is feasible to power wireless sensor device for a specific duty cycle with consistent source of vibration energy from two piezo elements. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
