Abstract
A multilayered electroactive polymer (EAP) device and a method of manufacturing the same is provided. The multilayered EAP device includes a plurality of unit layers. Each unit layer includes an EAP layer formed of an electroactive polymer (EAP), a protecting layer configured to prevent a material from penetrating into the EAP layer, and an active electrode formed using a conductive material. The protecting layer may be formed below the active layer or above the active layer. The active electrode may be interposed between two protecting layers.
