The invention relates to an arrangement comprising an expansible substrate (5, 6, 7, 8) and a strain sensor (1, 2, 3, 4) applied onto a surface of the substrate (5, 6, 7, 8). Thereby, the strain sensor (1, 2, 3, 4) is made from an ink composition, wherein the ink composition comprises a mixture of a conductive silver ink and a conductive carbon ink, wherein a ratio between the conductive silver ink and the conductive carbon ink lies in a range between 40:60 and 60:40. The invention further relates to an appropriate manufacturing method.
