Film constructions for interdigitated electrodes with bus bars and methods of making same

An interdigitated electrode film co-extruded with bus bars for thin film electronics or other devices. First electrode layers are located between first and second major surfaces of the film with a first bus bar electrically connecting and integrated with the first electrode layers. Second electrode layers are located between the first and second major surfaces with a second bus bar electrically connecting and integrated with the second electrode layers. The first electrode layers are interdigitated with the second electrode layers, and insulating layers electrically isolate the first bus bar and electrode layers from the second bus bar and electrode layers. The electrode films include multilayer films with vertical bus bars and multilane films with horizontal bus bars.
