a Schematic diagram of the fabrication process for IENG. b Optical image of a round Sm-PMN-PT/PVDF composite film with diameter of 9 cm. c Cross-section image of the composite film in b. d Optical image of a fabricated IENG with 7 units. Al electrodes on each side is connected as one electrode forming a three-dimensional intercalation electrode. e The corresponding cross-section image of IENG. Al electrodes, composite films and PET are marked by white arrows.
