The continuing work on the Micromechanical Flying Insect (MFI) aims to produce a 100 mg micro air vehicle with a wingspan of approximately 25 mm. Fundamental work by Dickinson et al. [1,2] showed the complicated unstable aerodynamics relied upon for small scale flapping flight. However, the unique wing stroke required for the necessary lift forces has not been achievable until recent advancements in MFI design.

Some of the most recent work has developed a lightweight control and power electronics board for tethered autonomous flight [3]. Further advancements in the technology have focused on optimizing the power output of our piezoelectric actuators by using a resonant dynamometer as a measurement tool.
