Acoustic Energy Harvesting Through MMPiezoelectric Harvester Model

Abstract

In recent years use of electronics devices such as electronic communication device and wireless sensor network are increasing rapidly since they consume low power, Furthermore increase in energy consumption has led researcher to focus on environmental energy utilization as it possesses several advantage in comparison with electrochemical battery. Moreover harvesting of environmental energy includes from raindrops, water current, and wind flow, thermal and solar has been few research area which is focused widely. In past several researcher focused on energy harvesting however these method has two main disadvantage either their material volume is large to adopt for real time or they obtain very low output power. Hence In this paper we focus on energy harvesting based on acoustic; further to achieve the optimal energy harvesting we propose a mechanism named MM-PEH(Multilayered multiple Piezoelectric Harvester ) we use lead zircon ate titnate as a piezoelectric generator; this cantilever type is used for harvesting sound energy from various loudspeaker with fair distance. Here we have employed multiple Piezoelectric Harvester in parallel for achieving high output power. Further evaluation is carried out in two stage; at first we plot graph, later further evaluation is carried out with several existing methodology and it is observed that our model achieves massive output power.
