  • Strain gauge, and system for spatially locating such gauges
    Patent number: 9200889
    Abstract: A strain gauge includes a substrate (2) for mounting an element (3) to be reversibly lengthened by a force applied while displaying a variation in the resistance thereof, the element (3) lengthening itself along an axis for measurement by the gauge. The gauge includes at least one contrast target (5, 6) capable of reflecting an incident light beam, the at least one contrast target (5, 6) being placed on the gauge in a predetermined position that makes it possible to predetermine the center of the axis (4), for measurement by the strain gauge (1), by detecting the position of the at least one contrast target (5, 6).
    Type: Grant
