Abstract
A radio frequency identification tag including a stretchable substrate () and an antenna () having a plurality of substantially concentric loops () 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 () disposed within an innermost loop () of the antenna and a second terminal () disposed outside an outermost loop () of the antenna (). The first terminal () is in electrical communication with a first end () of the antenna and the second terminal () is in electrical communication with a second end () of the antenna. The radio frequency identification tag may include an electrode making electrical connections with the first and second terminals.
