Title: Design and performance analysis of the mechanical structure of a piezoelectric generator by Von Karman vortexes for underwater energy harvesting
Issue Date: 10-Jun-2013
Keywords: energy harvesting; piezoelectricity; Von-Karman Vortex; fluid dynamics
Abstract: With the decrease in energy consumption of electronic sensors, the concept of harvesting renewable energy in human surrounding becomes a must. In this context, piezoelectric generators seems promising since they can harvests mechanical vibrations and in general energy available in nature. The aim of this paper is to design a piezoelectric generators, optimized for different kind of sensors and electronic equipments, able to work under the sea or into rivers, which can work with natural water vibrations generated by solid-fluid objects interactions (Von-Karman Vortex) and then to test the effectiveness of the device developing an electronic board to analyze the behavior of the generator.
