Classification: CPC G  H | IPC G  H

Claim 0:
1. A varifocal lens comprising:
a substrate having an inclined region;
a primary electrode disposed over the inclined region of the substrate;
a dielectric layer disposed over the primary electrode;
a deformable membrane disposed over and at least partially spaced away from the dielectric layer;
a secondary electrode disposed over a surface of the deformable membrane facing toward or away from the dielectric layer and overlying at least a portion of the primary electrode;
a hydrophilic layer disposed over the secondary electrode, the hydrophilic layer facing the dielectric layer; and
a primary fluid between the deformable membrane and the substrate, wherein:
the primary electrode and the secondary electrode have variable geometries that enable the primary electrode and secondary electrode to control, in response to an applied voltage, a shape of the deformable membrane.
