ELECTROHYDRODYNAMIC LIQUID LENS

摘要

Provided is an electrohydrodynamic liquid lens using an electrohydrodynamic flow of a fluid. The electrohydrodynamic liquid lens comprises: a housing having a ring-shaped passage formed therein; a first liquid for occupying a portion of the passage; a second liquid for occupying the remaining portion of the passage and maintaining a separated state from the first liquid; and a control electrode provided in the passage so as to be in contact with the first liquid. An interface at which the first liquid and the second liquid come into contact is formed with a curvature so as to function as a lens, and the control electrode changes the position of the interface by inducing the electrohydrodynamic flow of the first liquid.
