More Information
Summary:A liquid lens with flexible transparent active layers on both sides of a fluid is transformed along two distinct deformation axes. The flexible transparent active layers include piezoelectric materials that actuate the lens in response to applied voltage(s). The piezoelectric properties and actuation mechanism of the transparent layers are arranged to deform the lens cylindrically along different axes resulting in a net spherical deformation or a combination of spherical and cylindrical deformation with substantially less distortion than spherically deforming layers. The piezoelectric active layers may be polymer or ceramic with isotropic or anisotropic mechanical stiffness. Alternatively, a pair of transparent, internal layers are positioned between the front and rear surfaces. The active layers, front and/or rear, are dual layers affixed together with an adhesive or single layers.
