The research of flappingwing micro aerial vehicles (FMAVs) involves the study of bionics principles, quasisteadystate aerodynamics and prototypes development. This paper gives an overview of a novel method for designing and fabricating insectscale FMAVs from Shanghai Jiao Tong University. Each component is properly designed and reasonably arranged to reduce the assembly difficulties of such insectscale FMAV. Specifically, the design of the piezoelectric actuator has taken into account the electrical isolation and assembly issues. The transmission and the airframe are integrated into one component to avoid assembly difficulties. Fiber directions of the wing veins are reasonably arranged to possess high strength and high stiffness. As a result, this FMAV, which weighs 84mg with a wingspan of 35mm, can generate sufficient thrust to take off with a flapping amplitude approximately ±60° under the resonant wingbeat frequency of 100Hz.
