Dynamics of a three-dimensionally movable
microflight mechanism were analyzed both theoretically and experimentally.
The microflight mechanism is composed of magnetic
rotational wings that rotate and generate thrust in an alternating
magnetic field and a body with magnetic anisotropy that contributes
to attitude control. The device consisted of 2.5-mm-long
wings weighing 3.5 mg which were fabricated with MEMS technology.
A wing rotational frequency of 500 Hz provided enough
thrust for liftoff. Experimental data obtained through high-speed
camera images showgood agreement with theory and also quantify
the magnetic anisotropy of the microflight mechanism, which
cannot be estimated theoretically. Simultaneous actuation and attitude
control by an external magnetic field presented herein, which
culminated in simplification and small weight of the device and thus
the successful flight, is applicable to other MEMS devices.
