Abstract

In various embodiments, an electrode precursor material may be flowed into a manifold extrusion die having first and second manifold inlet openings. Further, an electroactive polymer precursor material may be flowed into the manifold extrusion die via a third manifold inlet opening such that the electroactive polymer precursor material is layered between alternating layers of the electrode precursor material from the first and second manifold inlet openings. Moreover, the electrode precursor material and the electroactive polymer precursor material may be extruded through a manifold outlet opening of the manifold extrusion die. Various other methods, systems, apparatuses, and materials are also disclosed.
