A transducer for assisting in measuring displacement or strain in an object of interest is described. It comprises a plate (1) having at least two end sections (5) for mounting the transducer to the object of interest. It furthermore comprises a flexible connection between the two end sections (5). The flexible connection comprises a plurality of rigid portions (3,8,9) and flexible interconnections (10) between the rigid portions (3,8,9) for allowing relative movement of the rigid portions (8, 9) with respect to each other. The flexible connection has a central section (2) comprising two rigid portions (8) spaced from each other over a distance and adapted for positioning a strain sensing element (4) at the spacing in between said two rigid portions. The rigid portions (3,8, 9) and flexible interconnections (10) are arranged so that a displacement applied to the end sections (5) results in a relative displacement at the spacing in the central section (2) that is larger than the relative displacement applied to the end sections (5).
