Integrated energy harvester for wireless sensor network

At present, autonomous wireless sensor network (WSN) components are extensively powered up using batteries. Due to limitations in batteries, it incurs huge maintenance cost and for remote and inaccessible areas battery replacement is simply impossible. To overcome this issue, an integrated Energy Harvester (EH) is proposed and developed here. Solar based EH has been identified as the most viable source of energy to be harvested for WSN components. Moreover, a novel chemical based EH is reported as the potential secondary source for harvesting energy because of its uninterrupted availability. By integrating both solar and chemical based EH, an integrated Energy Harvester (HEH) is successfully developed to power up WSN components. The book discusses on experimental results from the real time deployment, which shows that significantly enough energy is being harvested for perpetual operation of autonomous WSN components used in environmental parameter profiling.
