Schemes for harvesting energy from flag-like piezoelectric elements have been reported, both in water and wind. In this study, we briefly explore different geometries for scaling a wind based scheme to include four flag-like elements. We explore with flag thickness, flag length, and attachment device.
In our scheme, we use a sheet of overhead transparency as the main element. To the main element, we attach a piezoelectric sheet with an adhesive sheet. To each side of the piezoelectric element, we use conducting tape to attach the leads. Each element was attached with a flexible, duct-tape joint. The figure below shows the setup.
