Abstract
A transducer for assisting in measuring displacement or strain in an object of interest is described. A plate has at least two end sections for mounting the transducer. It comprises a flexible connection between the two end sections. The flexible connection comprises a plurality of rigid portions and flexible interconnections between the rigid portions for allowing relative movement of the rigid portions with respect to each other. The flexible connection has a central section substantially having a U-shape comprising two rigid portions spaced from each other over a distance and adapted for positioning a strain sensing element at the spacing in between said two rigid portions. The rigid portions and flexible interconnections are arranged so that a displacement applied to the end sections results in a relative displacement at the spacing in the central section that is larger than the relative displacement applied to the end sections.
