Electrospun piezoelectric polymers are being developed for use as a component on lightweight wings for micro - air vehicles ( MAV ) . The goal is to incorporate fibers with tailored properties to permit dynamic control and maneuverability during flight . In particular , electrospun fiber mats of two piezoelectric polymers were investigated to ascertain their potential for the MAV application . In the work reported here , the typical experimental set - up for electrospinning was modified to induce fiber orientation in the spun mats . The morphologies of the resulting fibers and fiber mats were evaluated for various experimental conditions , and a comparison between oriented and unoriented fiber mats was carried out .
