A review on piezoelectric energy harvesting system using vortex induced vibration

This paper reviews the energy harvesting from vortex induced vibrations using piezoelectric transducer. The process of obtaining the energy around a system and transform into viable electrical energy is known as power harvesting. Over the most recent couple of years, there has been an increase Research in the field of power generation. Vortex Induced Vibration is the motion induced on bluff body placed in the fluid flow due to alternate vortex shedding behind it, which produces discontinuous lift forces on it perpendicular to fluid flow. Normally, VIV is unwanted and reduced by careful design, in order to prevent mechanical failure of the vibrating structures such as high rise buildings, offshore structures, etc. However, in energy harnessing application from fluid flow, instead of expelling these vibrations, VIV will be exploited to transform these vibrations into a valuable resource of energy. The piezoelectric transducers utilizes these vortex induced vibrations which are generated by a fluid flow is one method that can be used for power harvesting. Harvesting energy from (VIV) vortex induced vibrations in flowing fluid has the ability to be a low-cost, low-impact, alternative to traditional power generation methods. In this treatise, we shall summarize principal results and discoveries concerning vortex induced vibration that have been performed in the area of power harvesting and we also study the different designs of piezoelectric transducers.
