G1N. A resistance strain gauge compris an electrically conductive foil element 4, Fig. 2 (e.g. of cupra nickel alloy), which may be formed by printed circuit techniques, sandwiched between two metal foils 1, 5 having a non-conductive film 2 on their surfaces adjacent the element. The element is held between the foils by an adhesive (e.g. a metal dust-filled resin type). The foils 1, 5 may be of aluminium and the film 2 may be aluminium oxide formed by anodic oxidation of the aluminium foil. The strain gauge is provided with an adhesive coating for attachment to a surface to be investigated, which coating may be a synthetic resin protected by a "strip off" paper or plastics film. Alternatively the strain gauge may be attached to a test article by soldering. Alternatively the foil element may be a thermocouple junction whereby the gauge measures temperature instead of strain.
