Patent ID: 7548009

Claim:
A miniature motor comprising: an actuator, the actuator comprising: a chamber; an electrically conductive aqueous layer accommodated in the chamber; a dielectric oily layer accommodated in the chamber, the oily layer contacting with the aqueous layer, thereby forming a contact interface therebetween; and a pair of electrodes configured for generating an electric field to induce the aqueous layer to produce an electrowetting effect; and a transmission assembly comprising: a thin film disposed at the contact interface, the thin film defining a first surface and a second surface opposite to the first surface, the first and second surfaces, respectively, facing towards the aqueous and oily layers, a hydrophilic coating and a hydrophobic coating being, respectively, formed on the first and second surfaces; and at least one transmission member, each transmission member having a first end and a second end opposite to the first end, the first end being connected to one of the hydrophilic coating and the hydrophobic coating of the thin film, the second end extending out of the chamber.
