Multilayer structure with embedded sensing functionalities and related method of manufacture

An integrated multilayer structure suitable for use in sensing applications, the multilayer structure comprising:

• at least one plastic layer having a first side and a second side opposite the first side;
• at least one film layer provided on both of the first and second sides of the at least one plastic layer;
• the at least one film layer on the first side of the at least one plastic layer comprising electronics incorporating reactance sensing electronics for sensing of one or more selected target quantities or qualities and conversion thereof into representative electrical signals, the sensing electronics comprising at least one electrode and a galvanic connection element configured to connect the electrode to an associated control circuitry driving the at least one electrode;
• and
• the at least one film layer on the second side of the at least one plastic layer comprising one or more features including at least one conductive feature, the one or more features being configured to shape an electromagnetic field to adapt a sensitivity or a directionality of a sensing response of the sensing electronics on the first side of the at least one plastic layer;
• and
• a film, first section of which defines at least portion of the at least one film layer on the first side of the at least one plastic layer and second section of which defines at least portion of the at least one film layer on the second side of the at least one plastic layer, wherein the first and second sections are connected by a third section extending between the first and second sections.

A method for manufacturing an integrated multilayer structure for sensing applications, comprising:

• obtaining a film;
• arranging the film with reactance sensing electronics for sensing of one or more selected target quantities or qualities on a surface of the film, and conversion thereof into representative electrical signals, the sensing electronics comprising at least one electrode and a galvanic connection element connecting the at least one electrode to an associated control circuitry driving the at least one electrode;
• arranging the film with one or more features including a conductive feature on the surface of the film, the one or more features being configured to shape an electromagnetic field to adapt a sensitivity or a directionality of the sensing response of the sensing, electronics;
• and
• arranging and configuring at least one plastic layer relative to the film so that the at least one plastic layer defines an integrated, intermediate layer between the sensing electronics and the one or more features hosted by the film.
