Flexible, stretchable RFID tags are formed by a pocket that is formed from one or more substrates and layers of adhesive, and an electronic circuit that is located within this pocket. The RFID tags can include a stretchable substrate and an electronic circuit attached to the stretchable substrate by one or a finite number of discrete spaced apart attachment locations. When the pocket is formed by relatively thick adhesive layers adhering together one or more flexible substrates to form an internal cavity, the electronic circuit is located within this cavity and either is not adhered to any of the substrates of the cavity, and is free to move about within the cavity, or the electronic circuit can be attached to a substrate by a thin layer of adhesive.

A method of patterning a conductive layer to form transparent electrical conductors that does not require etching is disclosed. The method includes peeling a strippable polymer layer from a substrate coated with the conductive layer to pattern the conductive layer. In some embodiments, a resist matrix material is patterned over the conductive layer to prevent removal of the conductive layer beneath the resist matrix material. In other embodiments, a liner having a pressure sensitive adhesive surface is brought into contact with the patterned strippable polymer material to remove both the patterned strippable polymer material and the conductive layer beneath it.

Surface-modified adhesives may be prepared by contacting an adhesive layer to an at least partially discontinuous layer on a releasing substrate and removing the adhesive layer such that at least a portion of the at least partially discontinuous layer adheres to the adhesive surface. The modified adhesive surface remains an adhesive surface. The modified adhesive layer can be used to prepare adhesive articles, including articles containing multiple surface-modified adhesive layers.
