Title:
ELECTROACTIVE ACTUATOR AND DEFORMABLE LENS WITH AN EXTENDED DEFORMATION RANGE
Document Type and Number:
WIPO Patent Application WO/2022/183084
Kind Code:
A3
Abstract:
An electromechanical actuator (1800) includes an electroactive layer (1810) disposed between a primary electrode (1822) and a secondary electrode (1824), and has a first curvature (A) when zero voltage is applied and a second curvature (B) when a non-zero voltage is applied between the electrodes. Preferably, the first and second curvatures are of equal magnitude but inverse sign. The actuator is particularly useful for a deformable liquid lens.
