Abstract:
1. A device for measuring deformation comprising: a) at least one strain gauge, producing a signal following a deformation, wherein the strain gauge is positioned on a face of a flexible support favoring elongation of the strain gauge, and wherein the face opposite the strain gauge of the flexible support, which is configured to be brought into contact with, or glued to, a test body has the deformation which it is desired to measure; b) at least one first substrate, including at least a signal processing electronic circuit and/or a signal transmission electronic circuit; and c) an elastic layer of material having elastic properties positioned between the gauge and the first substrate to assemble the strain gauge and the first substrate mechanically, and wherein the 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, the elastic layer having a hardness value less than 100 Shore A and being made of at least one of polyurethane, an elastomer, and a resin, wherein the device includes pins connecting the strain gauge and the first substrate electrically through the elastic layer.
