    Micro air vehicles (MAVs) are small portable flying machines designed to perform some specific tasks. Presently, the MAVs are being highly considered in applications like defense, security, environment protection, wildlife conservation, toy industry, construction, traffic management, and at times of disaster. Efforts were done in the past and are still being taken up to fulfill the need for smart MAVs. The authors examined a lightweight, safe wing using poly (vinyl chloride) PVDF and polyvinylidene fluoride PVC by using the electrospinning technique. The flapping test at room temperature tested the wings, and improved performance was observed in the heat-treated samples in comparison to non-heat treated samples. The modal analysis technique was also applied to understand the wings' safe working conditions, helpful in predicting the safe working conditions by the ANSYS software. The present study can be useful for designing and manufacturing new generation MAV wings for different applications.
