Abstract
An electronic device has three conductive polymer layers sandwiched between two external electrodes and two internal electrodes. The electrodes are staggered to create a first set of electrodes, in contact with a first terminal, alternating with a second set of electrodes in contact with a second terminal. The device is manufactured by: (1) providing (a) a first laminated substructure comprising a first polymer layer between first and second metal layers, (b) a second polymer layer, and (c) a second laminated substructure comprising a third polymer layer between third and fourth metal layers; (2) isolating selected areas of the second and third metal layers to form, respectively, first and second arrays of internal metal strips; (3) laminating the first and second laminated substructures to opposite surfaces of the second conductive polymer layer to form a laminated structure; (4) isolating selected areas of the first and fourth metal layers to form, respectively, first and second arrays of external metal strips; (5) forming insulation areas on the exterior surfaces of the external metal strips; and (6) forming a plurality of first terminals, each electrically connecting a metal st…
