A support substrate comprising an insulating plate made, for example, of ceramic material is provided. On one surface of the substrate is thin resistance element. The substrate is firmly fixed on its other face to a structure whose deformation is to be detected. The supported side of the substrate may be coated with an adhesive or cement substance to attach it to the structure. - Alternatively the substrate may be attached to the structure by retaining plates holding its edges, screwed to the structure. The resistance may comprise a pair of elements connected in an external bridge circuit.
