Abstract:
A device for measuring deformation including:a) at least one strain gauge (3), producing a signal following a deformation, where the said strain gauge is positioned on a face of a flexible support (32) favouring elongation of the strain gauge (3), and where the face opposite the strain gauge of the flexible support, which is intended to be brought into contact with, or glued to, a test body the deformation of which it is desired to measure,b) at least one first substrate, including at least signal processing means and/or signal transmission means,c) securing means (4, 5, 6) to assemble the strain gauge and the first substrate mechanically, where these means include a layer of material having elastic properties, called the elastic layer, positioned between the gauge and the first substrate, and where this elastic layer prevents the deformation of the gauge from being transmitted, or allows it to be transmitted as little as possible, to the first substrate (2, 20).
