1. A flexible printed circuit flex-PCB sensor comprising:
at least one sheet of electronically printable flexible material;
sensor cells printed on said at least one sheet and each sensor cell comprising at least one sensitive element and a circuit, wherein each sensitive element is arranged to measure a predetermined physical parameter and to obtain an associated measurement signal, and each circuit is arranged to receive said measurement signal and to process said measurement signal in order to obtain a corresponding output signal;
communication means connected to said sensor cells and arranged to transmit the digital signals coming from said sensor cells to a remote processing circuit;
wherein said at least one sheet is coiled according to a three-dimensional shape comprising a layered structure, wherein a plurality of layers of said sheet are placed side by side and form, in a region defined by sensing borders of the coiled and placed side by side plurality of layers, a sensing surface, said sensitive elements of each sensor cell being placed close to said sensing surface and said sensing surface being substantially perpendicular to the surface of said sheet.
