    Abstract: A film assembly or a multilayer stack can include an antenna having a spiral form disposed on a stretchable layer. The film assembly includes a stretchable substrate having opposite major top and bottom surfaces, and a first material disposed on the major top surface of the stretchable substrate in the form of a plurality of intersecting rows and columns making the film assembly less stretchable than the stretchable substrate. The rows and columns define a plurality of closed cells. An antenna for use in a radio frequency identification tag is disposed on the stretchable substrate in each closed cell and is isolated from the first material. The antenna includes an elongated electrically conductive electrode having a spiral form.

    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 innermost 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 first and second electrically conductive layers separated by at least first and second dielectric layers is also disclosed. The first dielectric layer is disposed on the first electrically conductive layer, and the second dielectric layer is disposed on the first dielectric layer. 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.
