A real-time dynamically tunable-focus microlens array made from a polymer-liquid-crystal (LC) composite is demonstrated. The polymer was first patterned in microlens array cavities by lamination, and the LC-monomer mixture was then injected to the molded polymer cavities and finally stabilized by UV light-induced networks. Using this new fabrication method, we demonstrated a lens with a spherical shape and a glazed surface. This LC-based microlens can reach approximately 100% light efficiency…

TLDR
A tunable microlens array by printing was demonstrated and the focal length of the lens array can be tuned by an electric field, which changes the index difference between liquid crystals and NOA65 due to the reorientation of the LC molecules.

Tunable microlens arrays using polymer network liquid crystal
Electrically controllable microlens array fabricated by anisotropic phase separation from liquid-crystal and polymer composite materials.
TLDR
Anisotropic phase separation has been used to fabricate an electrically switchable microlens array from nematic liquid crystals, which offer higher efficiency and greater light throughput than polymer dispersed devices.
