Abstract: A radio frequency identification tag including a stretchable substrate folded along a fold line to form top and bottom stretchable fold portions is described. Each fold portion has major top and bottom surfaces with the major top surface of the bottom fold portion facing the major bottom surface of the top fold portion. An antenna having a spiral form is disposed on the major top surface of the top fold portion. First and second terminals are disposed on the major top surface of the top fold portion and are in electrical communication with respective first and second ends of the antenna. A meandering electrode is disposed on the major bottom surface of the bottom fold portion and has first and second electrode ends making crimp connections with the respective first and second terminals.

Abstract: A radio frequency identification (RFID) tag that includes an antenna having a spiral form disposed on a major surface of a flexible substrate is described. The RFID tag includes a first terminal disposed at a first end of the antenna and a second terminal disposed at the second end of the antenna. The RFID tag may include a pad portion along the length of the antenna between the first and second ends for mounting an integrated circuit. Except for the pad portion, a radius of curvature of the antenna along at least 90 percent of a length of the antenna between the first and second ends is greater than about 0.1 mm and less than about 10 mm.

Abstract: A radio frequency identification tag including a stretchable substrate (105) and an antenna (110) having a plurality of substantially concentric loops (140) disposed on the substrate is described. A radius of curvature of the antenna along at least 90% of each loop of the antenna may be greater than about 0.1 mm and less than about 5 mm. The antenna includes a first terminal (124) disposed within an inner-most loop (145) of the antenna and a second terminal (126) disposed outside an outermost loop (147) of the antenna (110). The first terminal (124) is in electrical communication with a first end (120) of the antenna and the second terminal (126) is in electrical communication with a second end (122) of the antenna. The radio frequency identification tag may include an electrode making electrical connections with the first and second terminals.

Abstract: A multilayer dielectric film including a first dielectric layer made from a material having a first breakdown field strength and a second dielectric layer disposed on the first dielectric layer made from a material having a different breakdown filed strength. A multilayer film including a first electrically conductive layer, the first dielectric layer disposed on the first electrically conductive layer, the second dielectric layer disposed on the first dielectric layer, and a second electrically conductive layer disposed on the second dielectric layer is also disclosed. The first electrically conductive layer can have at least one of an average surface roughness of at least ten nanometers, a thickness of at least ten micrometers, or an average visible light transmission of up to ten percent. The first dielectric layer may be a polymer and typically has a lower dielectric constant than the second dielectric layer, which may be ceramic.
