A multilayer structure (100) comprises a flexible substrate film (102) having a first side and opposite second side, a number of conductive traces (108), optionally defining contact pads and/or conductors, printed on the first side of the substrate film by printed electronics technology for establishing a desired predetermined circuit design, a plastic layer (104) molded onto the first side of the substrate film (102) so as to enclose the circuit between the plastic layer and the first side of the substrate film (102), and a connector (114) in a form of a flexible flap for providing external electrical connection to the embedded circuit from the second, opposite side of the substrate film (102), the connector being defined by a portion of the substrate film (102) accommodating at least part of one or more of the printed conductive traces (108) and cut partially loose from the surrounding substrate material so as to establish the flap, the loose end of which is bendable away from the molded plastic layer to facilitate the establishment of said electrical connection with external element (118), such as a wire or connector, via the associated gap. A related method of manufacture is presented.
