Document Type and Number:
WIPO Patent Application WO/2020/091465
Kind Code:
A1
Abstract:
A fluidic lens according to the present invention comprises: a first membrane and a second membrane which face each other; a first means for forming a magnetic field in the first membrane and a second means which exhibits a magnetic force with respect to an external magnetic field formed in the second membrane; a fluid chamber which forms a space between the first membrane and the second membrane and is filled with fluid; and a supplementary chamber connected to the fluid chamber, wherein the second means generates a magnetic force via the magnetic field generated by the first means, thereby causing attraction and repulsion between the first membrane and the second membrane to adjust the focal length of the lens.
