A Millimeter-Scale Electrostatic Flapping-wing Actuator with High Lift-to-Weight Ratio

Abstract

We present a millimeter-scale, 3mg-weight electrostatic flapping-wing actuator which can generate lift force of 1.5mg under a stroke frequency of 80Hz, and makes the lift-to-weight ratio reach 0.5. As such, this work makes a key step in achieving electrostatic actuated FMAV's autonomous flight.
