Piezoelectricity has a wide range of applications. Some of these applications include piezoelectric actuators for positioning and vibrating control systems, power generators for environmental energy harvesting systems and sound production and detection. Piezoelectricity plays a big role in Piezoelectric Energy Harvesting Systems, which play a vital role in powering microelectronic devices with low-frequency operation. Here the developed Piezoelectric Energy Harvesting System prototype consists of a spoiler connected to a strut, placed in a vertical position. At the bottom of the strut there is a piezoelectric sheet. The developed Piezoelectric Energy Harvesting System serves to power microelectronic devices. As wind strikes the spoiler, the stagnation point creates a vortex that creates pressure on top of the airfoil, putting pressure on the strut consequently applying pressure on the piezoelectric sheet. As the pressure is applied to the strut, the spring brings the spoiler back up. This oscillation generates stress in the piezoelectric sheet to generate electric energy. This research aims to develop an efficient wind-based Piezoelectric Energy Harvesting Systems for low powered microelectronic devices on a plane.
