Abstract
An RF tag for inclusion in a smart label comprises a stiff substrate sized to be received in the smart label, an antenna carried by the substrate and an integrated circuit having a memory circuit carried by the substrate and coupled to the antenna by wire bonding. The substrate may be strain relieved, for example, by forming a pair of generally opposed serpentine edges on the substrate, or forming a plurality of grooves in at least one surface of the substrate. A smart label comprises the RF tag between a face sheet and an adhesive. A release liner may cover the adhesive. A compressably deformable material having a low viscoelastic modulus is received between the first surface of the substrate and the face sheet partially surrounding the circuit structure and wire bonds to hydrostatically protect against damage. A film layer with a blister may envelop the low viscoelastic modulus material.
