Abstract
The invention relates to a strain gauge including a substrate (2) for mounting an element (3) to be reversibly lengthened by means of a force applied while displaying a variation in the resistance thereof, said element (3) lengthening itself along an axis for measurement by said gauge. According to the invention, said gauge includes at least one contrast target (5, 6) capable of reflecting an incident light beam, said at least one contrast target (5, 6) being placed on said gauge in a predetermined position that makes it possible to predetermine the center of the axis (4), for measurement by said strain gauge (1), by detecting the position of said at least one contrast target (5, 6).
