Batch fabrication process of biomimetic wing with high flexibility of stiffness design for flapping-wing micro aerial vehicles

A lamination-based batch-fabrication process of biomimetic wing for flapping-wing micro aerial vehicles is presented. The key benefits of this process are: • One of the advantages of the process is high productivity; eight wings were successfully fabricated simultaneously in our experiment. • The wing fabricated with the reported process is made of soft polyimide and partially reinforced by a titanium layer. This configuration enables the flexible design of the bending stiffness distribution on the wing, which is the key specification for generating lift force. • The reinforcing material can be replaced with other metals or heat-resistant polymers, and the number of layers and layer thicknesses are also variable. This indicates that the reported process can be customized considerably to suit individual needs.
