<p>An electroactive optical device, in particular an electroactive lens, comprising an optical element (1) as well as an electroactive element (2) is described. The optical element (1) is an elastic solid, such as a gel or a polymer. The electroactive element (2) comprises a plurality of compliant electrodes (3a-3e) stacked on top of each other with an electroactive material (5) between them. The electroactive element (2) is surrounded by a rigid wall (4a, 4b), which provides two common contacts for the electrodes (3a-3e). In the absence of an applied electric voltage, the optical element (1) is in a mechanically relaxed state, which reduces undesired ageing effects. Upon application of a voltage to the electrodes (3a-3e) the optical element (2) is deformed.</p> |
