Rotational actuator of motor based on carbon nanotubes

A method of rotating a nanotube, comprising:

• (a) providing a nanotube attached to a rotor plate, said nanotube suspended at opposed portions between anchor pads on a substrate to permit rotational movement of the rotor plate without hindrance by the substrate, said nanotube and rotor plate are capable of 360° rotation relative to the substrate;
• (b) providing at least two stator electrodes adjacent the rotor plate;
• (c) applying out of phase voltages to the stator electrodes;
• and
• (d) applying a dc voltage offset to the stator voltages to the rotor plate.

• (b) providing at least two stator electrodes adjacent the rotor plate, wherein said providing comprises providing two stator electrode S1 and S2 on opposite sides of the nanotube and a stator electrode S3 approximately orthogonal to a line between S1 and S2;
• (c) applying out of phase voltages to the stator electrodes, wherein said applying further comprises applying out of phase, common frequency alternating voltages to stator electrodes S1 and S2;
• and
• (d) applying a dc voltage offset to the stator voltages to the rotor plate.
