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.
