Application: Bi-cylindrical piezoelectric actuated optical lens (Patent ID: US20240094445A1)

The patent filed by Meta Platforms Inc. describes a liquid lens with flexible transparent active layers on both sides of a fluid that can be deformed along two distinct axes using piezoelectric materials. These active layers are designed to deform the lens cylindrically along different axes, resulting in a net spherical deformation or a combination of spherical and cylindrical deformation with minimal distortion compared to traditional methods. The active layers can be made of polymer or ceramic with varying mechanical stiffness, and they can be arranged in dual layers affixed together with adhesive or as single layers.

The patent also includes claims for a transformable optical lens with specific configurations, such as non-parallel deformation axes, isotropic polymer layers with zero piezoelectric coupling factor, anisotropic ceramic layers with opposite signed coupling factors, and orthogonal deformation axes. Additionally, the method described in the patent involves attaching piezoelectric layers with electrodes together to form transparent active layers and then attaching these layers to a lens fluid container to create the transformable optical lens with non-parallel deformation axes. The method also includes setting the initial state of the lens to flat or curved based on the desired application.
