Microactuator Technology Introduction
Microactuators are small devices that can generate mechanical motion. They are classified into several types according to the mechanism that generates the motion. Some of them are introduced below.

①Electrostatic methods
This method uses the electrostatic force of opposing electrodes to generate mechanical motion.
This method can be created using a semiconductor process (MEMS technology) and has the advantage of being integrated with circuits.
②Electromagnetic method
This method uses electromagnetic force to generate mechanical motion. Electromagnetic force is generated using a small coil or permanent magnet.

③Artificial muscle method
This method uses a structure in which a special elastic polymer is sandwiched between electrodes, and the polymer deforms when voltage is applied between the electrodes. This method has the advantage of large deformation.
