A miniature motor includes an actuator and a transmission assembly. The actuator includes a chamber, an electrically conductive aqueous layer, a dielectric oily layer and two electrodes. The aqueous and oily layers are accommodated in the chamber. The oily layer contacts with the aqueous layer thereby forming a contact interface therebetween. The two electrodes are configured for producing an electric field to induce the aqueous layer to produce an electrowetting effect. The transmission assembly includes a thin film disposed at the interface and at least one transmission member. The thin film defines a first surface and a second surface, respectively, facing towards the aqueous and oily layers. A hydrophilic coating and a hydrophobic coating are, respectively, formed on the first and second surfaces. Each transmission member has a first end connected to one of the hydrophilic and hydrophobic coatings and a second end extending out of the chamber.
