POLYMER-BASED TUNABLE LENS, ELECTROACTIVE POLYMER THEREFOR, AND MANUFACTURING METHOD THEREFOR

摘要

The present invention relates to a technology for providing a polymer-based varifocal lens using an electroactive polymer. The present invention provides a polymer-based tunable lens comprising: a plate-shaped transparent electrode layer; an electroactive part disposed on the transparent electrode layer and formed of a transparent gel-like electroactive polymer; and an electrode part disposed on or outside the electroactive part so as to be electrically insulated from the transparent electrode layer, wherein the focal distance of the lens is tunable by applying voltage to the transparent electrode layer and the electroactive part so as to change the shape of the electroactive part.
