We designed and fabricated an innovative peacock-like micro hinge which adopts surface tension as the driving force. To prevent this micro hinge be out of our expecting range due to its inadequate stiffness, this study chose SU-8 negative photoresist which has high Yang modulus as the material and fabricated a light but wellcontrolled out-of-plane micro actuator by photolithography process. Subsequently, we attached this device to the PET film and testing its feasibility to MAVs by spraying working liquid on the micro hinge. Finally, we hope the novel idea of mounting and controlling the flight attitude can be integrated to MEMS technology and applied to flapping MAV or even NAV in the future.
