A method of manufacture and an integrated functional multilayer structure, includes a substrate film formed or formable so as to exhibit a selected shape; and a number of functional, preferably including optical, mechanical, optoelectrical, electrical and/or specifically, electronic, elements, such as conductors, insulators, components and/or integrated circuits, provided upon the substrate film in the proximity of the shape; wherein the substrate film has further been provided with a structural tuning element, optionally including an elongated, circumferential or other selected shape, said structural tuning element being configured to locally control induced deformation, optionally including stretching, bending, compression and/or shearing, of the substrate film within said proximity of the shape.

Integrated functional multilayer structure and method of manufacture therefor

Integrated multilayer structure suitable for use in sensing applications is disclosed including at least one plastic layer, at least one film layer provided on both sides of the plastic layer. A film layer on a first side of the plastic layer includes electronics incorporating reactance sensing electronics for sensing of selected target quantities, and conversion thereof into representative electrical signals. The sensing electronics include an electrode and a connection element for connecting the electrode to control circuitry. A film layer on a second side of the plastic layer includes features including one conductive feature that is configured to shape an electromagnetic field to adapt a sensitivity or directionality the sensing response of the sensing electronics on the first side of the plastic layer.
