摘要： A curable composition comprises a siloxane compound and a tetraalkyl orthotitanate. The siloxane compound comprises m divalent units represented by the formula —SiH(R1)O—, n divalent units represented by the formula —Si(R1)(OR2)O—, and p divalent units represented by the formula —Si(R1)2O—, wherein each R1 independently represents an alkyl group having from 1 to four carbon atoms, each R2 independently represents H or an alkyl group having from 1 to four carbon atoms, m and n are integers greater than or equal to 1, and p is an integer greater than or equal to 0. An at least partially cured curable composition and composite articles including the same are also disclosed.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

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.
