Renewable energy sources, such as wind, solar, geothermal, and gravitational are receiving increased attention due to the continuing
depletion of natural resources used for coal or gas-fired electrical power generation together with the associated environmental
emissions. An alternative approach to electrical power generation is to convert the available flow energy of a free-flowing fluid into
electrical energy, wind turbines being a prominent example. One of the lesser-known examples being the use of flexible
piezoelectric structures [1]. Piezoelectric materials have been in use for many years; however, with increasing concern about global
warming, piezoelectricity has gained significant importance in research and development for extracting energy from the
environment [2]. In this paper, we have comparatively studied the amplitude responses of both PVDF (Polyvinylidene fluoride) and
PZT (Lead zirconate titanate) structures to fluid flow with an objective of using piezoelectric materials as an efficient power
